Anybody got any real specs on the hp/tq of the DZ 302's? I always heard the actual numbers were astronomically higher than the 290/290 reported in the books by the corporate boys.

Koyote,
Smokey (rest his soul) was pulling 485 hp out of the specially cast porcupine headed 302's that GM gave him to evaluate. I'm sure the straight headed 302's weren't tuned to anywhere near this. My guess would be just under 400, remember Dave Strickler was beating 396 Camaros to win the world shcmpionship in 68 with his 302. those BB cars were 350 and 375 horse cars (25 when in the 65 Vette).

Not a real torque monster, plus GM had no real reason to screw with those numbers but HP was a little off, Since it was more or less a destroked 327/365 I would guess around 340-350 HP........ WITH HEADERS

I woulds say the #'s were not far off. I know someone who bult a copy of a 302 with all Chevy specs and it only made a little over 200hp at the rear wheels. Chevy only made them because to the size limit on that racing class. Put the same effort in a larger motor and it have more power. Unless of course your building an all original.

i have heard(from people like VIZARD & LINGENFELTER) that the 302 properly "tuned"(all clearances set to optimum)with headers would make an easy 380-400 h.p.,but this is at or above 7000 RPM.the DZ motor came with a 254 @.050" cam if i'm not mistaking,so it was a HIGH winder.
it was rated at 290 h.p. to sway the competition and to keep the insurance people minding their own bees wax.the 290 h.p. was rated at 5800 RPM and it probably made that there,but at 7000 it was a whole different ball game!

Well I am glad I have been friends with the men who built them in the first place....Jim Jones and Jim Travers of Traco Engineering. I have been through a FEW builds/rebuilds and the same dyno was used for the 302's 35 years ago....

With the "Winters" high rise, #186 heads and the most common solid that they used the actual output was between 420 and 450...mostly around the 430 hp area. Domes, 6" to 6.250" rods, teflon coating all the internals and about $2800.00 worth of head porting (by todays money standards)......Zinnnnnnggggggger at about 8200 rpm and shift.

Just as Jim was closing shop, he finished my 302 cid engine and it is a lot of fun, except for dodging cars on the road on the approach to light speed. Definatly not for a daily driver.

With todays head technology and cams available we wound around 480 hp with flat tops and no lead.....

I know of one that was dynoed last week (engine alone, not a chassis dyno), built to NHRA Stock Class specs (stock carb, intake, and cam, stamped rockers, stock valves and heads, pistons and rods) that made 425hp through headers and mufflers - pulls started at 5500, went to 7800 (mufflers required on dyno due to local sound ordinance). These things really make power when built and tuned properly, but you really gotta spool 'em up to see it.

JohnZ you are telling me that an NHRA stock class 302 through mufflers makes as much power as a full blown Traco race motor. Someone has a funny dyno.

i think the numbers sound right fir the 302. its easy to make over 400 h.p. on a short stroke motor at that kind of rpm. because of the short stroke and small cubes the heads have an easier time filling the cylinders and turning out those numbers. i'm into snowmobiles and these little 2 strokes now adays are making considerable power.a little 600 cc making 114 h.p.,but at 8000 RPM and the downfall is there's not alot of torque only about 70 lbs on the stock 600cc motors. the thing thats cool is the sleds only wiegh 480lbs,its a nice rocket! sooo you can wind the hell out of a motor and make h.p. but the torque down low will suffer. 302-400+h.p.-easy!
i think it was either baldwin motion or yenko ,had a daul quad 302 that made 480 h.p. that could have been purchased back then but i think it reved over 8000 RPM!

[This message has been edited by sldhd (edited 05-17-2001).]

It makes sense. Chevrolet knew then what Honda knows now. How else would Honda/Acura make 240 horsepower out of 125 cubic inches without a turbo?

You people don't understand my point Traco was the finest SB chev engine builder of the time. A NHRA stock motor is stock no 200hrs on the heads no 13to1 compression no 6.25 rods. I just don't see how the stock motor could make as much power as a Traco. Baldwin didn't have a 480 HP cross ram 302.



[This message has been edited by oger (edited 05-17-2001).]

From the magazines I have read, the 302 was under-rated(like everyone said) with a closer number of 325 on the sticker being more appropriate. This is for stock, street driven model.

Hey, I am not trying to be argumentative at all, just bringing up some scary news about "sport compacts"...(maybe I should put this in a different post, but I saw someone mention Acura)

I was watching some show on SpeedVision the other day and they were talking about Honda...

Well, I am sure you have all seen the Civics with the big tail pipe, big spoiler wing, and big rims and body ground effects... well, Honda has announced that for model year 2002 you will be able to buy Civics with the mods already done... also they will be offered with something like a 1.6L in line 4 that will put out 190 horses off the showroom floor.

Now, I know that 190 horses doesn't sound like much, but in a 2500 pound car it could move. A lot of power for a little motor too.

if we took the time to blur print a motor we would see how MUCH more power there is to be had. correct me if i'm wrong but when they say stock it means anything that came stock on the car? if so you can take those heads do a mild massage to them set all clearances to what "we" want. the Z-28 came with a windage tray(scaper) right,smooth the crank,zero deck block,degree in stock cam,make sure you have 16 1.5 rocker not 1.44 that has been seen on stock rockers.the list goes on and on. GMs tolerances are pretty lose. EVERY little bit adds up and thats how it will make 400 h.p.. granted it may not come on to 4500 rpm but it make the h.p. past 7000 RPM. remember 400 h.p. at 7800 rpm isn't like 400 h.p.at 5500 RPM. not to mention now adays we now ALOT more about how and why an engine makes h.p. with certain modifications instead of just guessing and saying we got lucky. the guy may have been the best in his time ,but its our time now. TECHNOLOGY.

As I remember, those engines, the 302's, were basically "race-ready" from the factory, with high-lift cams, optional dual-quads, etc. My copy of "How-to-Hotrod-small-block-Chevys" says that the the Trans-Am circuit 305's(which were 302's bored something like .020" over) made 460 hp at around 7500 rpm, so I think the 400+ figure is probably very accurate, just curious if any of you, personally, had dyno'd your OWN original, all-stock, 302.

<HR></BLOCKQUOTE>

Who is Traco? If he was getting less hp than that with a "full blown race motor" something must have been terribly wrong. Dad, meaning MY dad, built a 430hp, single carb 283 his junior year of high school, in 1970!

Well the one number #1 bench racing question of all time - how much horsepower does a certain engine make??

Unless you have corrected (for altitude & humidity)real engine dyno numbers you are just talking hot air. So funny dyno - maybe different dyno different engine? Unless they are corrected the same engine will vary when tested under different conditions. Of course the same engine tested on several dynos will also vary in Horsepower and Torque. Then consider the differences in components and compression.

The one person I know is right - is Chacane67 because Traco built more 302's than anyone. Who was Traco Engineering? The West Coast engine builders for Penske's Camaros in the Trans Am racing days. Traco also did engine development work for Chevrolet. At any one time during the racing years they had two engines in Penske's Camaros, two spares and two engines in overhaul.

I'm sure they could get more HP out of the engine if Traco built one today?

So how much HP in a 302?? Just depends on what apples and oranges you want to compare? I just re-read and old 70's Chevy mag article with a 302 built with 12.1 compression and old Edelbrock Scorpion II manifold and a Murray Jensen 830 cfm carb made 501 hp @ 8000rpm

After reading this thread I went out to the garage opened the hood on my fully restored '69 Z/28 and we just smiled at each other.

Life is good.

John

The thing that is missing in this mess is HP is just a bragging rights issue. People seem to have a problem with the truth if you think that a 302 makes 500HP in stock form go ahead no one will change your mind and it doesn't really matter. If you are happy with your Z28 who cares how much HP it makes.

OneMoreCamaro,

I love going out to the garage and having my Camaro smile back at me. It makes me happy.

I have to agree with Oger that it is just about braggin rights and doens't really matter. With that said, I was just reading an article about the Penske Camaro in one of my mags and they claim it made 440 @ 7400rpm with a single 4 barrell. Of course, that is the full out race motor.

He, He!!!!
I do know that my little homemade PAS 301 I put together years ago outta junkyard UNBALANCED parts w/ a used little Duntov cam and Q-Jet carb and CI manifold was a blast ta drive once you got it up on the cam!!!! Torque be damned!!! IMHO. pdq67

The engine in question is not a "street" 302; it's a very carefully blueprinted and balanced package, optimized within factory tolerances, built specifically for drag racing, and spends its entire life at wide-open throttle pushing a set of 5.13 gears in a trailered '68 Camaro running NHRA "E" Stock. Note again the range of the pulls (5500-7800); anything below 5500 is unimportant in this application. Traco built great engines, but they had to work over a much wider power band than this application, with much greater reliability. Tuning for this particular application is very different than for a typical Trans-Am car. This may be the first full-bodied legal factory "E" stock car in the 10's (it ran 11.13 last year) - not bad for our little 302.

I know what a NHRA stock class motor is. Traco was able to do just about anything they wanted with the orgional parts. A stock class motor can only be blueprinted that is it.

I know this is kind of off the subject but has anyone seen what a 302 will do with a twin turbo setup? I have yet to see one, those engines are rare as it is. I was going to build a chev 302 until I saw how hard it is to find a crankshaft for it.

We can argue hp all day concerning the little 302 motor but the proof is in the high rpm FUN factor!!

Drop even my junk 301 in a light car, then gear and tire right and become "Jack, the Giant-killer!"...

AND I don't doubt these numbers at all, even for the old 283 motor b/c the suckers flat cooked up top and I have read enough OLD mags through the years that verified them b/c of wins they printed that happened!!

AND a 292" motor is just a little Z- motor too, imho..... AND I think we got into a discussion like this a while back about full-house 292 motors that made like above 500 hp, all tunnel-rammed and all up above 9 to 10,000 rpm in dedicated STRIP-only shoe-boxes WAAAAY back there!!

pdq67

Somewhere here in my office I have a dyno sheet from a stock 302 pulling around 350 horse. and that topped out at around 6k. A good running 302 in NHRA will dyno over 450 horse and run past 8k

My '68 Z/28's 302 internals are all stock and NOT blueprinted. Untouched heads with original springs and stamped rockers, stock intake manifold. Original Holley and M21. My car has 1 3/4" Hooker s/c's. Note: About half a dozen of my rockers were way out of adjustment. A friends' '69 Z/28's 302 is almost all stock except he has a 750 Demon and uses 1 5/8" Hooker s/c's. All pulls on a Dynojet using the STD adjustment on a hot and humid July day, sorry but I didn't record the exact weather specs.

Both cars made between 241 and 245 RWHP on all pulls.

Peak power on my car was at between 6200 and 6400.

Peak power on his car was around 5800.

Using an 15% drivetrain loss you get flywheel power between 283 and 288.

Using an 18% drivetrain loss you get flywheel power between 293 and 299.

If 101 octane "custom supreme" pump gas were still available today, I would still be running my homemade 302. I loved the revs(8000 rpm) and HP(about 375).

so, does this get the award for "oldest thread ever resurrected"?
that being said, i might still build a modern LT1 based 302. i've got the cop car LT1, i just need to find a good Caprice L99 forthe bottom end..
figure with a HOT cam and the EFI, that little sucker would be a blast. maybe put it in the '30 Model A 5 window high boy i wanna build..

I wouldnt go with the hot cam....youde start making power about the time the hydraulic roller gives out. Either solid lifter or solid roller would be the only way to fly....

Stockers are WAYYYY cool.

http://www.classracer.com/pics/ficacci.jpg

i just bought the august car craft magazine, theres an article and pics in there of the smokey yunick 68 trans am 302 camaro motor that vic eldebrock now owns.
it says that the motor was turning out 482 HP at 7,500 rpm with 337 TQ with the dual carb setup.
it goes into detail about each motor part......heads etc.....and what was done to each...........tells some secrets too....
very interesting article.

Stockers are WAYYYY cool.

http://www.classracer.com/pics/ficacci.jpg

That kinda puts the term "NHRA Stocker" in perspective...

yup, thats Steve Facacci's car, very nice guy, and its a stick shift car.

I was reviewing this thread, and thought about a horsepower computer I had seen at:

http://www.speedworldmotorplex.com/calc.htm

based on a 3400 Lb car and 11.13 ET, we get 487 Rear wheel HP, and 575 HP at the flywheel. All I can say is wow!!!

Rob

Anyone that thinks a record holder NHRA stock Eliminator motor is just some factory stock parts that have been clearanced is GROSSLY misinformed.

They're using backcut rings, ring spacers, LOW LOW drag ring packages and wall finishes, obscenely fast ramp "stocker grind" cams, Schubeck lifters, H-11 springs (in stock configuration, of course) and a myriad of other tricks in the areas of reducing friction, parasitic losses and oil control.

The fast guys will flow dozens of head castings and intake castings to find a couple that work the best and then spend hours making them just right.

The valve seat area is a big area that they concentrate on, but every single nut, bolt, and assembly in THE ENTIRE CAR is tweaked to perfection.

The competitive and record holding stockers in the mid and upper classes are absolute works of mechanical art and deserve your attention during a Division race or National event.

Randy

I'm not sure about horsepower, but there is a 66 Corvette and a 69 fake big block Camaro in my area both with GM 502 crate motors that won't mess with a balanced and blueprinted 302 in a 80 mph rolling start, again. If I'm going to give up 200 cubic inches I'm going run under my terms and about 5000 rpm in 3rd gear is where a 302 really gets rolling.

He, He!!

Yes, running across the back country on the flat, straight county blacktop roads way back then..

But not nowadays b/c the Conservation Dept. planted way too many Deer, as well as all the Cops running the back roads looking for Meth. Cookers here!!

Back in 76' my dad used to run his 69 RS Z at the track. Std bore 302, Heads massaged slightly with a three angle valve job and some basic cleanup, but no porting.etc. Flat tappet Crower 550 lift cam, 255 dur., 780 dz carb ,Edelbrock tarantula intake, Accel dual point and hooker headers. Car was stock bodied RS, all steel 3450 w/o driver,5:13 12 bolt posi. Left the line and shifted at 8 grand. Best 1/4 mile ET 11.57, 118 MPH. She would flat out SCREAM...Unfortunately, on the last run, the cam shaft broke in half, causing a nasty engine failure which reduced the DZ block and its contents to a very large paperweight! :(

This is a great thread for the younger guys like myself. Great conversation. Keep it going. :thumbsup:

It may have been deleted years ago, but I posted a thread 2-3 years ago that was basically a condensed version of a 302 camaro bolt on parts exercise that was tested at the strip...I don't believe they did any dyno testing. Granted, its not as old as this thread :D I'll see if I can find it...

I guess the old thread is gone. When I get home I'll see if I can find that old magazine and repost the info.

From "Hot-Rod" magazine January 1969.
(4) 1/4 mile test results driven by John Dianna (HRM's assoc. editor)
1-4.56:1 rear, closed headers, and street tires =14.34 @ 101.35
2-Same gears, open headers, Casler 9.50x14 tires =13.79 @ 103.68
3-Same as 2, plus carb & ignition work =13.64 @ 104.28
4-4.88:1 gears, M&H 9.50x14 tires, E/T bars, & Hurst shifter =13.11 @ 106.76
The existing "National Record" in D/Stock was 12.31. Dave Strickler took the World Final Stock Eliminator win in a '69 DZ with a "high 11's E.T."
Hope it "clears up" some questions. Thanks, Gary in N.Y.

Everything I've read on the 302 (actual hp) 400

I myself can attest to an original DZ 302 being pulled from a bone stock, low mile Z/28 when it was being race fitted about 15 years ago. The engine was dyno'd on a true engine Dyno, built and ran by world known TFAA tuner Les Davenport where the engine was tested on 6 runs with 347 HP being it's best stock performance at 3600' above sea level.

Thats the only true test I have ever seen on an original unmolested and low mileage DZ motor. I think the car had about 10,000 miles on it and it was later wrecked while being raced in British Columbia in the early 90's while owned by Greg (Noodle) Miller.

Mister Copo - What was the engine configuration for the 347hp dyno test? Open headers or manifolds and full exhaust? Were any engine accessories or smog system hooked up? Were the numbers corrected or uncorrected?

Thanks. -Neil

mister copo
where in british columbia? do you know?
mission or westwood perhaps.
your not a canuck are you?

I wouldnt go with the hot cam....youde start making power about the time the hydraulic roller gives out. Either solid lifter or solid roller would be the only way to fly....


Comp "R" lifters and an AFR hydra rev kit

spinning my LT1 (stock bottom end) well over 7k (little bigger cam though hehe)

Man Youve Been Looking At Your Z For 21 Years,,,, How Do You Do That ,,,, Id Be Going Nutsssssss

Well, I bought my 68 RS 302 in Colorado Springs almost two months ago. The 302 is not a factory original. The previous owner built it with a friend who does machine work for a race team. Driving on the interstate through Nebraska at 130 MPH with more pedal was the coolest thing I have ever done!!!!! I have never owned a car with a motor like this one. It was like living in "Cannonball Run!!!" LMAO

He, He!!

A Buddy of mine I met about '72 or so in College knew my B-i-L had a '69 Z-28 and he said he loved how it "marched across the blacktop bottom north of his home town running about 140!!

North of Huntsville, MO up towards Thomas Hill Power Plant....

AND he drove like that and got into more trouble b/c of it as time went by.

Good Article , lots of input,, To the gentleman complaining about availability of 302 cranks.. There are many out there if you want a stocker and many crank firms can build what you want , how you want, for all the money you got.

Where did it peak?

From what I have read 302's were made for trans racing and not straight line
Racing. They are lacking in the torque dept which effects the 0-60 and 1/4 mile times. They drove a 302 last week on Dream Car garage on the Speed Channel and the driver commented on not much power off the line
do to lack of torque. The car did do very well on the oval track. I would agree with the other guys that the 302 could possibly make 380+ when it was wound up all the way.

the guy on dream car garage wasnt reving it to 7000 rpm and dropping the clutch either ! :)
he did say he liked the boss 302 mustang almost as much as the 69 Z.......but the Z was a better all around car

also the the likes of the "LIL HOSS" [ not sure of the spelling here ] didnt have any problem winning there classes and setting records in there day with 302's.........kicken BB butt too as i remember.

Man Youve Been Looking At Your Z For 21 Years,,,, How Do You Do That ,,,, Id Be Going Nutsssssss

It would take just as long to tell the story!!!

Just the way things have worked out...

Had to post to this thread.
Couldn't help myself. Just went for a cruise, dumped the clutch at 4,500 and blasted through the gears....
302's are fun...
Just don't think I'd pull my original motor stocker past 6500 though.
I'm confident in my rebuild but I'd cry for years if I damaged the original DZ motor.

Todd

The main problem with the first Boss 302 was that it had 2.23"/1.71" valves!

I think the next years saw 2.19"/1.71" valves installed to try to gain some lowend. But it still didn't help all that much, imho..

He, He!! Valves like a BB Chevy for feeding a whole lot smaller motor!

Not good at all for any sort of grunt!

pdq67

I messed around with quite a few for drag race. 450 horsepower numbers were fairly common, but to get them to perform you neede 4.88 or 5.13 and a 4 speed. Also remeber even today dyno numbers differ greatly from dyno to dyno. I'm sure it was worse in the late 60, early 70s. Loved 302 back then, but with todays gas and advances in cam, carbs, torque converters etc wouldn't want one now. But nothing replaces the sound of a high revving 302.

I have that "69" Hot Rod magazine in front of me, all shifts were at 6,000 rpm's. Come on!!!!!!!!!!!! In Feb. 1969, I bought one because of this mag. article, but I never shifted at 6 grand, more like 7,000 -7,500 with stock setup and Doug's headers. After installing an Isky 505 roller/ultra rev. kit, crane roller rockers,850 Holley double pumper and blueprinting, I shifted at 8,000. It ate 375 horse Rat's for lunch, and Boss 302's were a joke. The biggest increase came with 4:88's. it would barely chirp the tires from a rolling start,but when the revs came(5,500) it turned into a rocket. The car is still in existence and storage.

LOL.....Z's rule!

In a previous thread (http://www.camaros.net/forums/showthread.php?t=55500) my friend was getting all sorts of bogus advice from scott shafiroff on his DZ 302. His motor went from ~290 to 245 at the rear tires. We pulled the motor out and brought it down to Jerry McNeish the same weekend as fall carlisle. Anyway, he just got a call from our hero Jerry on Saturday and the motor is done (only dyno tuning remains). He told Chad the motor will make between 450-500 fwhp. I'll be anxiously awaiting the dyno results because if it really makes that power then I'm gonna find another 4-bolt block (original MO block and crank get set aside) and have a similar buildup done. He's using the fuelie heads.

Back in 1972 I bought a 69 Z28 with little or no options on it from the Local Chevrolet Dealer where I lived in Miami at the time for $1695 it had 9K on it thus bringing the price higher then other 69s were selling for at the time it was bone stock. It ran great but I got beat by friends 70 Trans Am till I installed headers and a little tuning then beat him pretty good. It IMHO it was the most fun car to drive of all the cars I have owned and whatever horsepower you make with the Z28 is all upstairs in the RPM range

the original 1969 Z/28 heads are referred to as "fuelie heads" or "camel humps" or "camel heads"

the "camel" refers to the front side cast mark on the heads

"fuelie" I believe because the fuel injected vettes from the 60's came with nearly the same identical head designs - someone please correct me if I'm wrong
