Thread: Heads Port and Polish, Cam, etc

Welcome to CHR:

Can you tell us a bit more about what car you're running this engine in? Rear end ratio?

The cam your looking at needs a lot of compression and lives best at awfully high (for the street) RPMS.

I'm also curious why you're using a 700R4 - the 3.06 first allows you to really jump at take off but the huge (47%) jump to 1.63 second gear can be a big disappointment. It would be like first to third on a four speed manual. I would venture a guess that you rarely see the OD. Maybe a solid TH400 would help in the overall goal.

Regards,
Glenn

The car is an 82 Corvette. Compression is 10.5:1. The rear end is a 3.73. Why a 700R4? Well...it's what was in the car. Had it rebuild and built up a bit. I've never driven a TH400 but the OD is pretty nice with the 3.73 gears. Really want a Tremec 5 or 6 speed conversion but $$$. I am considering a 4l60E upgrade for the fine tuning of the shift points. Much less money than a 6 speed conversion.

Really searching for 500hp and with the nitrous cam and heads that's in it, I think I'm sitting about 450.

I sure do appreciate everyone's comments! A lot of knowledge and experience here.
