Im buying parts for my rebuild and im trying to decide what pistons to get i want the best ones at the lowest price, on a tight budget I was looking at Speed pro forged pistons for $215 a set but the compression is 9.6:1 on 64cc combustioon chambers so Im tryign to figure out what the compression would be on LT1 heads. I was thinking between 10.2 and 10.6 but thats just a guess. is there a formula to figure comression?
thanks for any help you can offer.


im open to any suggestion anybody might have on rebuild ideas or parts.

 

I would say for the price the best piston to get is SRP.
