What's the chance that roller lifters would run on a (new) stovebolt camshaft without damaging the lobes? I realize the lobe lift curve would look a little oddball- - - -just wondering if the combination might "Gee-Haw" without causing a major disaster of some sort! That would certainly solve the "ZDDP in the oil" problem!

Edit: It looks like a hydraulic roller lifter for a late-1990's Dodge 3.8 Liter V6 will fit the stovebolt lifter bore if the bore is sleeved down to a .904" diameter. With a little tinkering with pushrod design, I believe I can come up with an ultra-quiet engine that never needs a valve adjustment, and one that can run modern motor oil to boot!
