I CC'd the heads and piston tops last night. These pistons really suck. The 670s came out at 75cc and the pistons at tdc came out at 26cc. using a compression calculator this works out to 8.6 to 1.
Lets pick a new cam for this engine. I am not partial to any one brand but I do like a lopy idle.
This is my combination.
67 Firebird.
th350 and will mach the torque converter to cam.
8.5" 3.08 posi. will be changing to 3.42
Hooker 1 5/8 headers
Performer intake.
sucky 8 eyebrow pistons.
8.6 to 1 compression
any ideas?
