Here you go;im bout to put a high compression zc pistons into my z6 how good would it run and wut would xactly be the compression ive heard different things
Hey Supastyl, are you using A6 pistons on your Y8? What's your compression right now? Were your running on 91 octane gas that you had to retard the dizzy that much? We have 96 octane here and I'll be reaching around 11.2:1 c.r. on my build so would you say I'd still end up pulling timing?
ok i did it on 4 diff. cr calculator sites.^your calculations are wrong for both your setup and the z6 set up unless your head is REALLY milled.
the z6 head/block with z6 headgasket is right at 12:1
Yea, PM7/P29 sit 1mm/.040" down on Z6/A6 bore.
