Swapping out a Voodoo
You need to call a cam grinder with ALL a the info and they can grind something that won't have an issue.
You'd be surprised that many fast rate lobes don't eat up near as much P/V as the slower lobes.
I'm running .620 gross lift and my pistons are .045 out of the hole and I still have more P/V than I need.
Regardless, check you P/V every time. Doo-doo occurs.
