Well I can say that I have wiped out a few solid lifter cams in my 45 years of building big block mopars. So there, I said it, I learned from my mistakes from not looking for lifter rotation, not pre -priming the engine, not having the timing set right on so the engine would fire right off, not pre-priming the carb with gas, not removing the inner springs to reduce pressure on the cam, not having the battery fully charged and there's probably a few more items. I know now that when I turn the key the engine will fire up so fast it's almost scary.
