Reading back through my previous post,I feel the "Head Flow" is probably more a limit to more power & revs with this cam than the size of the Cam itself. I have my distributor set-up with a light spring. It has 20 degrees initial for starting & instantly goes to 36 once running. In top gear I can go to full-throttle once I'm up to about 1800 without getting the "clatters"(pinking).
