well i wasn't looking for 12:1 cuz i kinda would like my motor to last a little while but i was debating on 9:1, 10:1, or 11.5:1 and the way its looking its gunna be 10:1 but seeing as i have never fully built a motor i would like some input on what all i should do to help with horsepower and longevity of my motor.... i was thinking JE 10:1 pistons, crower rods, ACL race bearings and thrust washers but i'm still not sure of my top end... would aftermarket springs, retainers, etc.. (skunk2) or type r internals be better and its either gunna be crower cams or skunk2 cams i'm not set on anything right now but if somebody could tell me what would work and wouldn't be a good idea... or if anybody on here works at a machine shop and builds motors could point be in the right direction because i am planning on building this within the next month or so
