hydraulic or solid? flat tappet or roller?
I'll probably suggest smaller on the race board than most, but I'd keep .050 duration down to the 224-230 range for .050 duration on the intake for good streetability.
hydraulic, I'd look at a voodoo 670403 or comp XE275HL, or similar .050 duration hughes grind.
juice roller, I'd look at a comp XR274HR or XR280HR or similar duration hughes grind....
solid, probably something designed for a ford .875" lifter for a flat tappet--I'd be real leery of a comp MM lobe cam for low maintainence street duty...roller, again I wouldn't go super aggressive (even though you don't have to worry so much about eating lobes) to get some semblance of sping life. for a solid, I'd probably look for one that has 230-245 .050 duration on the intake.
