what are they doing with your engine?...a reverse engineering exercise on performance setups?....once you set your overall combo (heads, pistons, intake, injectors, etc), the cam that will support your performance expectations is designed.....PtV issues?....need to find out after the cam is installed, timed, and measured, and provide for clearance reqs.......or performance gain will not be accomplished.....IMHO.

i'll be doing the same thing with my current cam. once my valve covers come ovv i will use the spring method of measuring my current ptv clearence and i will see how much room i have left... this will help me choose a cam that will fit without any issues.

completly incorrect... measuring his PTV clearence off the current cam will tell them how much bigger they can go... shows how much YOU know

......"Similar duration/lift" cams will have different overlap values/timing dependant on the lobe profile, LSA, phase event timings and installation (advanced/@0°/retarded)...reason why you have cams with advertised overlap in the 60°-65° range, but overlap @.05" in the -2° to +15° range....and could only be "safely" taken care of by measuring it installed, having a custom cam ground with that "limitation", knowing the cam's VOTC value (which I think Isky cams are the only ones that provide it)........or finding out about the possibility of a clearance problem the "bent valves" way.
