Have a recent build and have to tear down for a head gasket/head issue and would like to change the cam while I'm back in it. 1998 RCSB Dakota with 3:23, 28" tires. Engine is a forged 440 with six pack rods, Speed Pro pistons, Source heads, 9.3:1, Tri Y and 2.5" duals through a Flowmaster X chamber big body muffler, and is topped with an Edlebrock Pro-Flo4 efi. Orginal build was with a Lunati 702 cam. Any Guru's on here have any advice?
