306 Combo?

[87gt17815]

Hey man sounds like you got a killer combo. You should be lookin at anywhere between 400-425 horsepower when tuned in. But i feel that the carb may be a little on the large side. A 650 would have probobly been a better choice. As far as the heads they are a good choice and are very economical also. The next big up grade you will need will be tranny. The stock t-5 will not hold up behind a centerforce. I speak from experiance. the shock of a centerforce is to much for a stock t-5 behind a built motor. Some people get lucky and they hold up but more times than not they blow up. Give Bob Hanlon a call to get a good opinion on the perfect clutch.
