340 Cam Comparison

This thread is not about 318s or 360s. Appreciate the input but please try to stay on topic.

Btw.. when I measured compression on this motor before pulling it apart it averaged 180 psi with what appears to be a stock 340 cam and 2.02 J heads on my gauge. I’m putting 63 cc heads on so I think I’ll have plenty of compression potential.
