I have just received my money from uncle same and am really looking at putting my engine together. I want to go with a little different combo please tell me what you think.
396 2 bolt block .060, studs on mains
factory steel crank
stock length rods, arp wave lock bolts
10.25/1 forged floating pistons
Brodix -1 OEFI oval port heads
RPM intake and demon 750 carb
1.7:1 comp cams roller rockers.
Now life gets complicated, I was thinking roller cam until the recent post I read here.
So what about a solid?
maybe a CC 282S or a Crane 282F?
I want close to 500hp and good tq out of the motor.. any suggestions? Maybe power numbers for this combo?
How about the heads? would I yield better power with a set of edelbrock RPMs?
I am ready to start just need some guidance on what to do, so I leave it up to the experts! Thanks up front,
Tony

Not too many months ago there was a 396 build up in either Car Craft or Popular Hot Rodding. Did you see it? It made an interesting case for a stout, affordable 396.

Camaro Performers I think is what you're talking about, I just got done reading the article. they used a comp cams street roller grind with 236/242 duration at .050, 0.647/.654 lift and 110 degree seperation. It sounds mild but the engine put out over 500 horses. I can give more information on the engine if you want, the article is sitting in front of me.

Rick and lil_beast_67,
I have the "mean little rodent" series in both super Chevy and Camaro Performers. I think this is the article you both are referring to, Great articles. That is where I concluded the brodix heads have some bite to them.
-My big question is on the roller cam idea. I recently read a post on this topic here and it sounded like solid rollers stink on the street. I don't want to pay $800 plus for the setup that I have to change out in less then 10,000 miles. I hope to find a solid grind that can give good power numbers for this set up.
-I also wonder if the performer rpm heads might be a better choice for this setup..
- I finally caved in and decided I will go BBC over the small block, but as always I "have to be different" then everyone else on the block!
Thanks for the replies guys!
Tony

Sounds like a great combo so far.
As for the cam give Comp Cams a call, sure you have to wait to get a tech but its worth it. I would think a flat tappet cam should work fine. You will need sometning like the XE284 to get you close to 480 -500 HP in 402 and you will have to spin it a little close to 6600 RPM

The 2 bolt studed block will hold up fine. As for rods if you dont have a set ( or they need to be rebuilt) check out GMMP 7/16 rods from Sallee Chevrolt . You get NEW 4340 forged rods with good 7/16 bolts ready to bolt in for $350.00 I have had these past 7200 rpm( on accident)

I dont have any experiance with the Brodix Ovals but I have built a .030 over 396 with the Signature Series aluminum heads from GM with the 2.25 / 1.88 valves and they do clear the bore but make sure you notch the tops like the 375 HP 396. These are the same head as the Performers for BBs

I've always been a little leary of any hydraulic lifter cam that is intended to spin over 6000, especially over 6500 RPM's.

I helped a friend with the XE284 in a 327 SBC extensively this summer and the engine just starts to fade over 6500 RPM. It should pull like crazy to 7000+ with that cam and it just dies. We've gone the whole route with heads, carbs, intake, ignition, valve springs - everything and we're certain the hydraulic lifters are the culprit.

I'm not a BBC or roller cam guru, but the two solid grinds you mention look real good to me. I don't know the lobe separation on the Crane cam, but in general Crane uses wider separation angles than Comp - this moves the RPM band up a tad AND smoothes the idle a little over a cam with the same duration numbers and a tighter separation angle. (I personally like Comp's 110 LSA for larger torque monster engines, wider LSA's work better on small cube high winders IMO)

I'll play with Desktop Dyno a bit and post again if I have any ideas - but it looks good to me.

Good luck with the build!

68 Camaro, 383 small block with TH350 trans. 11.98's at 111mph and never trailered.

IMHO, the 282S sounds like it is about right for your combination. I just ran it through Dyno2000 with small tube open headers and 2.19"/1.88" valves and got something like 518hp at 6000rpm and 506t at 4500rpm.

I know it is just a sim. program, but if you are within - 5 to 7%, you will have one sweet running BB!

Hey guys thanks for the input. I think the solid by cc is the best way to go. I will call them tomarrow and see what they recomend.
PDQ67 518hp wow! Good #s on both sides. Like you said even if off by 7% those are good numbers I could live with. Thanks again,
Tony

How about a small cube bbc that can make just short of 600hp, and runs 10.70's @ 125 mph in a 3500 lb car. This engine also has GM 781 iron truck heads (no porting), mild Comp Cams Xtreme Energy street roller cam, and 10.5 to 1 compression.

I'll make you a nice deal on it if you wanna run mid 10's in your car http://www.camaros.net/forum/wink.gif

Actually, the Brodix -1 OEFI is a real good head, but is way too expensive IMO. $2000 for a pair of aluminum oval port heads compared to a pair of GM iron heads that will run the same ET or quicker for half the cost...your choice.

If money were no option, the Brodix would make a good choice, but reworked stock heads will do the same job, just as well if not better. The 70 lbs weight savings of aluminum heads isn't worth the extra $1000 IMO.

79 Malibu, 414 ci BBC, 3550 lbs.
10.75 @ 123.8 mph, 1.50 60'

Many(++++) years ago I put together a 402BBC with oval port closed chamber heads (2.19/1.88 valves) 10.25 compression and a Holley single plane with a 750cfm DP and 2" hedman headers. The cam I used was the 282S and I loved it. I could get away with high test pump gas and a little octane boost or 50/50 mix with race gas. In a 3600# car, T350 2800 stall and 3.73 gear with slapper bars it ran 12.50's @119mph.BTW the trans was slippin bad too...

All right, I called Comp Cams, they suggested I step it up a bit with a 294S cam. What do you guys think of this one? PDQ67, any suggestions? Does anybody think I will gain any power by going with the RPM heads? I think the smaller ports of the brodix heads will give better acceleration, but not sure.
-Slowazzbu... Thanks for the offer but I am enjoying the build it yourself thing right now..Outstanding numbers though!
Please keep giving me input, I don't want to buy the wrong combo of parts..Thanks,
Tony

Tony,

Actually, I was just kidding about selling my lil 414 rat http://www.camaros.net/forum/smile.gif

Why not consider using a pair of real mild prepped GM 781 or 049 oval port heads? If not GM heads, the use the Merlin oval ports.

I know they will run just as well if not better than the brodix, yet cost half as much.

slowazzbu,
Got it http://www.camaros.net/forum/wink.gif I am not to worried about the cost thing. I almost bought the grumpy Jenkins heads but I decided that a little savings over the front will be good for my application. Hate to call it pro touring but I do have a few High dollar left & right turn accessories.. I would like to get the most out of them. Most would say go small block however, I have a soft spot for the 396, (the engine in my first Camaro) SO as I digress, am going with the 396 and would rather keep the aluminum heads unless my budget changes. Like they say “ If you have the money why not get what you want http://www.camaros.net/forum/smile.gif” Definitely food for thought though, thanks!
Tony

Tony if your motor runs half as good as Todds 414 be real happy. I still haven't completely figured out why it runs so good but it sure does.

oger (mike),

It's all in the BSE Powered combination. http://www.camaros.net/forum/wink.gif http://www.camaros.net/forum/biggrin.gif

In all honesty, I never would have guessed the lil' 414 would run as quick as it has. I really thought 10.90's were all it had in it. I suppose I've got nothing to complain about http://www.camaros.net/forum/smile.gif

AJBorski,

Get hold of GGriffin, in Moberly, MO b/c he has a 10.75 to 1 CR. or thereabouts .040" over 402 with the 294S cam in it. His heads are closed chambered ovals. He can give you the straight-skinny on the cam. Greg used ta peek in every once in a while but he mighta got busy, if you know what I mean. I saw his red '69, last weekend. Tell him I said hello.

As for the Brodix aluminum heads, buy what you want and can afford, but if I had it to do over again, I woulda bought a cheap set of Canfield aluminum heads from Competition Products, but they weren't on the market that I knew of when I got my C.I. oval Merlins. pdq67

pdq67,
I will try and find him. Thanks everyone for your input, as I am still a green horn at this, every comment is appreciated.
Tony
