Re: My 1968 C-20 Golden Anniversary Project

Forget to screw in the spark plug = Leak & again
Chamber volume 63 cc
Intake runner 164 cc
Exhaust runner 52 cc

Small block 64cc: Amount to reduce chamber volume by 1 cc (milling): 0.0055"
Remember: In the outer area cylinder heads up to 0.3 mm (0.011811") removed, means more or less matching.
