8.1:1 CR?
Found some JE/SRP Pistons, .020 over,
guy want a good price for them, but in a DOHC ZC this is going to give me 8.1:1 CR. I want to keep my 9.5:1. How much of a difference will this make. I know its safe detenation wise, but I'm wanting 320whp on a .60/.63 T3.
Getting Delta Regrinds and a Custom IM.
EDIT: Just double checked and with the bore I get a bit over 8.2:1

Well by search by part numbers and finding the dome height, 7.9:1 CR is what I would yeild. Too low. Yes shaving the head is possible, but for the price of machining of the overbore and shaving the head, I could buy the right pistons.
Plus with the DOHC ZC good luck finding a thinner HG!!!
I'm gonna run 18-21 psi. Just ordered my Eagle Rods.
Big Garrets live in my backyard!! My Bro-In-Law has them all the time, if a bigger housing is required, I would have no pronb finding one.
