V2.75 cam specs

I'm looking for some info on the v2.75 cam in a p pump. Just wanting to know if any one has mm's to lift conversion numbers??? I don't think a 215 cam chart numbers work or at least my dial indicator isn't matching numbers.

I'm giving up on the dial and going with the fill spill method and degree wheel.

If you were feeling charitable, you could pop the dial back in after you find LPC and list the plunger lift by degree.

But couldnt that be different pump to pump? Depending how the barrel was shimmed.

Certainly, but at least there would be some numbers on the cam profile floating around for the next guy. Or map the whole thing from base circle to max lift. Then the next guy just has to figure out where his port closure is and can do some basic arithmetic to make his own lift chart.

I've got my pump cam completely mapped out and I still time mine by spill port, timing by plunger lift seems too inaccurate.

I haven't mapped out this one, just both stock options and a couple others. Hamilton has a nice thread with some numbers that might be helpful for you though. http://www.competitiondiesel.com/for...d.php?t=188858
