raising compression?

(1/1)

stang1:
whats up guys i have a 1986 mustang gt and i am building a 5.0 engine for it i have a set of j 302 heads with a stage 3 port with a after market cam the heads are shaved down i am wondering my options for raiseing compression?

rmodel65:
J 302?? you mean J code from a 60 model mustang?

Jeff73Mach1:
either pistons that have less dish, no dish or pop ups will raise compression.  Without changing heads, shaving the heads and zero decking the block can only give you a small increase, but make it necessary to alter the intake to fit with the changes.

Of course a turbo or supercharge will sort of raise the compression too!

Steel shim head gaskets.
