ok if i have 11:1 with a 64cc head wat will it be with a 72cc head??


i know there are compression calculators but i dont know all the necessary i just know with my rotating assembly and a 64cc head i will have 11:1

i know this is a quicky for some1 here thanks

 

9.99:1 assuming all other variables being equal.

 

so get another set of heads or just use those??

 

Depends on intended use of the engine and what compression ratio your shooting for.

 

well i want it for a project car itll be a short stroke ls that turns high rpms with a 240ish cam
