i'm wondering if 11.8-12.1 cp. is high enough to run crower stg 3 cams.

bottom end
84mm 11.5 je pistons
eagle h-beam rods
arp rod bolts
gsr head
5 angle valve job
arp head studs
port n polished
lightened rockers
crower valves, springs, & retainers.
crower stg3s.

or should i get the 12.5 pistons?
would i be able to run and tune it properly with 94 octane with no additives? with the compression going a little higher depending on the pistons with the gsr head..


anyone running stg3s with 11.5?
