It amazes me with ma mopar, that they can never seem to give an accurate number for their cam specs. My 5.2L cam was no where near the printed specs I could find. Mine measured out to 244/256 183/195 .411/.431. The printed specs I found was 250/264 .431/.431. So the #'s DionR has doesn't surprise me in the least.
Probably because the spec’d, specs for the cam as the engineers designed it, what costs will allow it & the quality control of the grinder produce are 3 different things. Also how there measured on what machine.
