I don't remember the grind on that cam now, (that was back in the late 1990s) it was a solid lifter lifter custom ground for a pump gas street motor. The heads where some new Mopar replacement castings (1980s to 1993 or so)that the customer had, he had bought out a B.K Dodge dealership inventory of D.C. parts before I met him. He was a successful SO CA lawyer working in L.A, CA. He had earned his way through college and law school working in a body shop part time and really liked Mopars He bought every Hi Po part he could get
The pistons where cut for stock 5/64 rings, not low tension oil rings per his instructions I'm thinking it was right at 10.5 to 1 compression ratio, a tad high for today pump gas
That motor out performed (HP per C.I.) another bigger C.I. aluminum Dart headed 526 C.I motor with a stock OEM X ram with a set of John Bauman prepped SS carbs. that I assembled for him That was embarrassing I still don't know why
