Mopar Cam 284/484 or 288/497
I'm ok with an MP cam. By why not a solid lifter? You can restrict oil to the lifters, make more power...all good things?
I like the P4529969, or if you have the P/V clearance, the P4529970.
I would lash them at .020/.022 hot and go for it.
Other than that, a custom grind.
