Thanks for the info. I put trust in a friend's advice whose a reputable Mopar builder & has built some great motors that made good power w/ the Engle cams & your recommendations verified his prefrence for Engle.
Got a flat tappet 504/514 lift intake/exhaust & 272/280 duration on a 112 lobe separation.
Should run well in a 451 stroker.
Doug @ engle was really helpful.
