well i dont know what to think on this cam. i attached pics of 540 233 stacked, and as I mentioned, there are no poly locks so I believe its hydraulic cam. so big d, i think its contradicts what that wallace chart says. I took a couple pics of lifters if that will help any. let me know if any other thoughts.
Jim - i dont quite follow on the measurement piece. are you saying to measure the total amount of travel the lifter generates from lowest point of cam rotation to the highest? and maybe using top of lifter bore as a static reference point? on a related but simplistic note - I now understand the rocker multiplier (thanks big d) - so lets say lobe lift without the multiplier is .300. is that saying the lobe lift is .300 of one inch? so roughly 1/3 of 1 inch?
