I currently have a 68 Camaro with a 350 bored out .060, forged pistons and crank. S/R Torquer 67cc heads with 2.02 and 1.6 valves. I am using the Edelbrock RPM Air-GAp intake and an HEI ignition. I also have a large tube exhaust system with crossover and Flowmaster mufflers. I am considering installing SuperComp headers. Is it possible to get close to 400 horse out of this by changing the cam? Any recommendations? Thanks.

I think you can get four hundo out of that with a cam. I put in a mid grade xtreme energy comp cam in my 350 and I'm pushing about 4. I have larger CC heads but I'm not bored out and you are. I think it is quite possible. comp cam # 12-238-2, it has a nice lope but not too radical. Good luck

Yes it is quite possible.First I would recomend a pocket port and gasket match.Use FelPro intake gasket#1205, this will fit the RPM's ports perfectly.
Some people will tell you the gasket match is not nesicary,but I beg to differ.I too have S/R Torquers(I have an early set though) and a Performer RPM and I will tell you this:The S/R Torquers intake ports are smaller than the RPM manifolds intake ports(they may have corrected this by now).This hampers the flow because the air/fuel mixture will come out of the intake and slam into part of the heads casting.My head porter told me the heads intake ports were biger, I'm sorry I took his word for it.
400HP should be obtainable with a camshaft that has 225-235 intake duration at.050.To get 400HP with the 225 at .050 cam will take good tuning.
Oh..and stick with a 1&5/8inch header.1&3/4inch and larger will take away too much torque in the power band you are working in.

Rodsters, trying to give a cam recommendation without knowing your compression/gearing is dumb guessing. You want me to dumb guess?? Didn't think so.

Cam duration is linked to the compression required to support low rpm cylinder filling.

Need gear/stall as well.

Dont waste your money on the Super Comps or any Hooker. They outright suck and you;re paying for name only. Got my Hooker from JetHot, $425 had to ding #5 tube for steering rod. Friend just bought Super Comps from JetHot, $700 one is good, one points at the floorboard.

Thorley/Dynomax/Sanderson. etc. Just not Hooker. Dont go there, I did and I stepped in crap.

Think it very doable to pull 400 HP out of a 350. Think solid or solid roller. Ultradyne has some quick ramp hydraulics as well. You'll need to run it up to 6500 or so to pull that kind of number. If you have >10.1 CR, try the smallest Crane solid, custom ground on a 108 LSA.

Oh thats another thing, you run P/B or other vacuum accesories??? Once you get into cam selection you'll have to decide what idle quality you are looking for. The nastier idle, the more power for any given cam range.

I currently have TRW 9.72:1 Forged pistons. The rear gears are presently 2.73:1, but I just picked up a 4.10:1 12 bolt last weekend which will probably be part of my winter project. I really don't want to buy the Super Comps. I presently have Dynomax headers that work fine, but the number 1 tube is too close to the number 3 spark plug boot. My current cam is a comp cams 268H with 218 duration at .050 and .464 lift. I just want a little more. Thanks!

Gene,

I know alot of BB guys having major problems with Hookers. But, the Super Comps for small blocks do fit perfect. I have the 1 3/4 and a buddy has 1 7/8. Perfect fit.

For you rodsters, I recommend 1 5/8 headers. Instead of HP, tell us what ET you want to hit. 400hp to one is 325 to another.

Lonnie, and yes it might be Hooker BBC for 67 Chevelles only. just expect more for the long dollar you pay is all.

RODSTERS, tranny ratios/stall and deisred amount of lope please. I have some ideas but want to narrow them down for ya.

I have a stock TH350 with a stock converter. Lope is hard to describe. I definately want it to idle on the street without sounding like it is going to die.
