I am looking for the compression ratio and the cc's of the factory heads. I am going to get new pistons and cam but need some info First.

Thank you,
Brian

the only way to know the cc is to actually measure your heads
someone elses heads will be different then yours

Contains head casting numbers and their application:

Compression ratio & power specs:

IMO, much better chance that somebody knows the cylinder head cc's on one of the two boards in the links than at this site.

u2slo I just read that today and there is no mention of the cc in that wright up at all. thanks for the help. I will have to pull the motor tomarrow anyway
