H cams explanation please

Post by TRFell »

Hi I'm familiar with the marking anomaly on the 1955 and 1957 cams but what does the H marking mean on the 3 dot type?

I think it stands for higher lift profile on the cam.

H designates it's a High lift cam for roadsters, not the same as SH which is an even higher lift cam for scramblers.
