Re: Ported Chevy 083 heads, the tpi project

A low power 302, you could just get a 305 or better still a 307.

It will at least be more important than the resonance.

Re: Push rod pinch on restricted intake manifold.

? I know we have to have the PRP move air around a turn, and that it has to be there, but what if that air is already slower and can make the turn easier than a well flowing induction system? Usually the answer to opening up the pinch would be NO. Its going to kill your lower end tq and so forth Hu...

Re: How can I get this to seal?

Looks like an easy job, just not making too much mess is the actual challenge.

Re: 11.5 compression, Iron Head, 91 octane

Save the thick gaskets for a last resort. Don't use studs and you can change them in the car if you get that desperate.

Re: 11.5 compression, Iron Head, 91 octane

Stroked Windsor with a single plane and a decent size cam, should get by, don't put a dual plane or a long runner efi manifold on it.

Why not soften the chambers and then it'll be ready for a shot of nitrous as well.

If you go to Calder you'll have to drop in and put it on the individual wheel scales.

Re: Inexpensive 350 Build

I want to put an anti roll on there. The differential isn't right, too tight, the front brakes drag, and a good trans would finish the project, then we would have something. But you know I like the car and the smooth idle, its a nice change, I think we got a decent back up race car when the other c...

Re: Inexpensive 350 Build

Next the rear suspension will have to be addressed. Any details here you care to share? I see a wheels up launch so there's something going on that's peaked my 3rd gen Camaro interest!

Does it need to go on a diet?
Nah, just get to optimise your wheel weights for best launch.

Re: 401 sbc ready for the Dyno

Did you manage any A to B testing with the Progressive compared your best results ignition-wise? This came back to me while watching this 406 dyno test on the Unity MotorSports Garage channel. If you do/have seen it, what are your thoughts on the results? https://www.youtube.com/watch?v=_MMCnP8570U...
