Just seen one of your new posts...11.45@118mph. A pretty substantial difference since last year. What changed? Damn good run for a "mild" 388 graemlins/thumbsup.gif

Mine is supposed to FINALLY leave the machine shop next week. Good thing too...I was about to stick a 350 in there :eek:

Wholy moly! I'd like to get that with my 412. What's the deal? What's the secret?

Maybe he went on a big diet...

Maybe thats his "altitude corrected" time tongue.gif

Must be! Sea level makes everything look better :cool:

You sure it can run that fast with a single plane and 3.55 gears :D ;) tongue.gif
Fill us in - on whats new.

This post is all in jest: Do you think a magician is going to tell his secrets? I don't think so.....

It is a wonderment to see us SBC boys run with/faster than most BBC boys. Some of the cars there were NOS aided to arrive faster than 11 seconds.

I know I've started something here......not that I'm egging anybody on......I ain't.

But I don't think I'd tell you how my little stick matches your big stick........

Down here in Texas we have a bunch of local little sticks (SB guys) showing up at the car shows,
running low 11s, and a pumps gas 406 runnin 10.0s - so dont ever underestimate the "little sticks"!
Isnt there a GM zz430 here thats close to brakin in the 11s?

Infact a friend with a 383, 4spd, 69 camaro just sold his stock Twised Wedge heads to me, and got
a ported set by TEA. I ported his Victor jr. (plenum & port match). The car has gone 11.5s@117, he
just got it back together - we'll be headin to the track soon. If any one is interested what a difference
a good set of ported heads can do on a mid 11sec car, I can post the results.

Geez Travis . . . SSShhhhhhh !! Was trying to sneak that by you guys. LOL. Good to hear you're getting a motor back soon.

OK, yes it ran good last night. We had some good air, temps in the high 50's, low humidity, and no wind. Track was a little greasy though, it was only the second T&T night this year and there were a lot of front wheel drive weenies out there doing long smokey radial-tire burnouts in the box and dragging water all over the place. :rolleyes:

Changes from last year . . . well, I caged it so no more having to short shift and sandbag. The cage added an extra 100 lbs, although the scales weren't open last night so I don't know for sure.

I lost 25 lbs off my rear wheels with lighter rims. I also lost some weight off my butt over the winter, so there's another 20 lbs. But the car is still all steel and with driver will weigh in at about 3550-3575#.

I went through the engine over the winter and did a little clean up work on the heads ;) I also fixed a fuel supply problem that was making me lean out on the top end.

Really that's all I did . . . and I'm still running an "obsolete" Magnum solid cam, a 3.55 gear, and a "boat anchor" single plane intake ;) honest.

Only bad thing is that I may have hurt my rear end. It was popping when I went around corners on the way home. A little howl too :eek:

Awesome numbers, just curious what kind of 60ft times you have? The car must launch very nicely.

Rich

Thats good mph for that heavy weight! If it was 3300lbs it would go 120+mph.
Its a good combo. Do you have 1 3/4" headers? what exhaust? X-pipe? Some of these
may help. Since the roll bar added 100lbs (wish you'd have done a moly bar - only 50lbs),
do you plan loosing some more weight? I remember not too long ago you were runnin 12.teens,
and now youre not too far from low 11s. How about a roller cam? Good to see such progress.

Sorry to hear about the rear end (wait, that didn't sound right...). I've been wondering when it was going to go away as they usually fail long before now at your level. Are you still running an auburn or did you switch to an eaton? If you need to change rearends, and can't find a 8.5" 10 bolt, let me know...I know where a bunch of them are.

So whats the goal this year...11.2's? graemlins/thumbsup.gif

Travis, I just crawled out from under the car and found the rear end problem. I took a couple teeth off the ring gear. I'll start a separate post in the drivetrain section. Wish I knew where there a couple 8.5" rears around here -- shipping from OK to MI would be what - $200 or so ? Feel like driving 1/2 way to Michigan? -- I could meet you 1/2 way j/k . . . LOL

67RS502 -- I run Hedman 1-3/4" headers with the Flowmaster American Thunder pipes and Dynomax Ultraflow mufflers. Just an ordinary H pipe.

I thought about (and was saving for) a roller cam, but looks like my side-job money is going into a new rear end instead.

67ragtp -- 60' times were 1.605 sec with 1-2" of air under the front tires. We got video (super 8 not digital) and it was really a smooth launch, not violent at all.

graemlins/thumbsup.gif Nice improvement. What rims and what tires?

Told ya he lost weight! :D

Thanks, was running 15x8 steel Rallys with 26x11.5x15 Hoosier QTPs. Still running same tires with Centerline 15x8.5s. Forgot the name of my new Centerlines, I bought them to match my old street rims and reduce some rotating weight.

I thought about the moly roll bar, but it would have been much more difficult to weld and would have still weighed about 65 lbs according to S&W.

Congrats on the new best times. Looks like you should be in the 7.20's now. ;)

I was planning a little port work on my 383 and a slight bump in compression myself. That was until I decided to step up to the plate and get into the BBC arena. Found myself a nice little '67 roller and just recently stumbled upon a 650 HP LS-7 454. :D Nice little engine for the money....hoping for 10.50's or better with 4.56's and an ATI 8" that flashes to ~5500. That's the basic combo so far.

Kinda feel like I gave up on my goal of 6.99 with the Coupe. Woulda got there had I done some work this winter.

Eric, very nice! Especially considering the mild gear.

Rafael, I would definitely post the results from Dan's camaro. I think its representative of alot of S/S rides on this forum. Be sure to include the flow #'s before and after. Let me know when ya'll are ready to head to the track, I think I'm more anxious than Dan to see the results.

I think Eric's improving times are a product of his continually tuning, researching, and tweaking his combo.

Rod

Thanks Garret -- best of luck with that new BBC. You were pretty close to 6.xx's already . . . would have been nice to see you make it. It starts to get expensive getting those last few hundredths out of a pump gas N/A small block doesn't it?

I was thinking of swapping in a Lunati Harold 288/296-108* solid FT for some back-to-back testing this summer for grins. I'd like to see if it would go a tenth or two faster with the more agressive lobes -- I just hope my valve train parts would hold up as well as they did with the old Magnum lobes.

Nice numbers Eric! What are your full incremental times and mph? With a 118 mph you could get that thing into the 11.2x's perhaps with a converter swap.

And what is your secret for yanking the front tires?!?! :eek: That is a dream of mine that keep eluding me. graemlins/clonk.gif I cut 1.56 60ft. but I think the tires are staying put.

Actually I haven't done any video since I put the roller set up in there but none of my friends have said anything. I also only made one trip to the track since I put the roll bar in. Maybe the stiffer chassis will help.

Anyway, tonight is my first trip to the track this season so we'll see how it goes! graemlins/hurray.gif

ERIC68, Are you looking for another rear? I have my 10 bolt out of my 68, I bought a 12 bolt, I live in Michigan, down by Lake St Clair.

Eric/ Travis...I'm in Stillwater and get awesome freight discounts...can get it there pretty cheap.... let me know if I can ever help. smile.gif

Thanks for the offers guys, I really appreciate it. graemlins/beers.gif

For now I am going to pop in a new set of gears -- I'm going to try a 3.73 this time. I really liked my 3.55's but they cost like $30 more a set :eek: besides, a little more gear might help the ET a little. We'll see. I hope they're OK on the freeway.

Here are those incrementals Greg . . .

R/T_____.465 :eek: (too focussed on staging, not on the light)
60'_____1.605
330'____4.702
1/8_____7.298
MPH_____94.87
1000'___9.546
1/4_____11.455
MPH_____117.97

I agree more converter would make it go faster . . . a tight 8" that flashes to 4500 would probably be perfect. Only problem is that until they invent an 8" that will flash to 4500, footbrake to less than 3000, and be reasonably tight down to 2000 I'm kind of stuck. I drive it 3000-4000 street miles a season.

Keep doing what you're doing Eric. You are running VERY well with a "true" street car. Anyone can go fast with a big stall and other race parts. The challenge is doing it with streetable parts and pump gas.

Before you pop for a new set of gears you might want to hit your local wrecking yards and see if you can find a Nova 8.5" or a Ford 9" out of a 70 Cougar. I found a 9" posi for $60, I am hanging on to it for my 71 Nova or I would offer it to you. I would be interested to see what a set of 3.73's would do in your combo. I know you will keep us posted.

Eric, my 8" ATI has all the above characteristics and will flash to 5200 in 3rd from a 15mph roll. I'm sure it would be even tighter behind your motor. I can cruise through the neighborhood at 1500rpm and cannot hold the rear tires above a ~2800rpm footbrake.

They're not cheap though.

Just throw in some 4.56's and an 8" ATI......just make sure you plan for a racing stripe in your underwear. :D

Only $699 during the winter sale! Gotta love those ATI Treemasters. I'm getting an even looser one when I drop the BBC in my Camaro. ;)

8" ATI & 4.56's eh? I think that would be too much gear for me though -- 4.10's would have me running 6500-6600 through the traps in the 1320, would be closer to 7 grand with a 4.56. Not to mention those long freeway trips from here to Detroit each summer. I'll probably get a new converter when I build a new motor in a year or two (hoping to get 20,000 miles and 4-5 seasons out of this one).

Not sure about the incontinence problems though . . . the closest I've come to that problem was riding in my friend's 427 powered 69. It started going sideways after he got the front tires about 12" off the ground . . . and that was on the old industrial drive :eek: (note to self - don't ever ride with Ron again)

So Royce . . . when is this blown beast of yours going to make a pass? I'm anxious to see what this monster of yours is going to run. Just make sure you always stage in the right lane so you can see the tree LOL.

I've heard about getting a 9" from a 70 Cougar once before . . . don't they have the same axle width and perch location as a 1st gen? or do you need to move the perches? I'm swapping in a new set of gears now (I'm halfway done) but I will be looking for a core so that I can built a new rear for the car in the next year or two.

So Garret, what is this new BBC combo you're building? Care to share any details with us?

Eric,
The 70 Cougar is a very close fit. I know a lot of guys have just boled them in. Depends on who you ask some say it's a direct bolt in. I think there is actually 1/8" difference in the spring perch locations.

I hope to make a pass pretty soon I still only have about 300 miles on it. I am excited to see what it will run and if it will stay together. I am also a little scuurred, it feels VERY powerful (I don't know if the 8.5" is going to like it very much). I am not legal for anything under 11 second (which was my original goal when I built the car). So I know I will only get a pass or two before they ask me to leave. I'll let you know how it goes. I am pretty sure it will be sometime next month.

Hey Royce,
Email me before you go to the track. I'd like to tag along...

Will do Aaron.

Congrats on the new best ET's!

PS a 9" rear will slow you down.

Eric, excellent times. Don't get into the I want to go faster to the point you have a car that really isn't streetable but isn't a real race car either. An 11.40 small block car with 3.55s is an awfull good runner. I think I might play a little with the tuning but make no major changes. Good luck.

Coupe
Whats your BB plan/combo... if you dont mind. Whats it going in? a chevelle?
Also consider this (most people miss it), when choosing a gear look at tire size and
"MPH" you'll be running. If you run a 28" tire with 456 gears and you run 130mph, with
converter slippage you'll be revving around 7500rpm thru the traps. If it runs over 130mph,
which it probably will, you'll really be buzzin it. So unless you have a motor which make
power at 7500 - make sure you look at your gear ratio choice closely, as rpm goes up
quick with mph and a bunch of gear. A 4.11 to 4.33 may work better for you, and let the
converter launch the car. Just my thoughts.

John
Dan said the car is running well, he's been beating on it on the street some, and feels
everything is ok and we'll be heading out to the track with it in a week or two. I'll let
you know when - if you wanna go, and I'll post the results. But it may take more then
one trip to really see the potential of the ported heads, some tunnin/tweakin and better
cooler weather would be great.

Garret, are you building the motor like Ed's, or like Marty's?
