What Would be the best way to raise compression on a ZC motor to around 12.1 just new pistons? or is there a better way cause i love high compression and i wanna get me some juice

 

Mill the head, but you won't be getting 12:1 w/ just that. Mill the head & get some high comp pistons & you'll be set

 

youll definately have to get some aftermarket pistons...the zc head has huge chambers. if you deck the block 0.040" mill the head 0.030 and run a y8 HG youll still only have about 11.6:1. i think endyn has some pistons for the zc...or they have them in development.

 

sweet right now im running a mini me swap with a y8 head and Y8 gasket with like 40 PSI fuel i love it
