Combo Advice 340

If it were me, I'd have a custom cam made, usign that info, plus flow numbers on the heads. "pro race ported" sounds like they are good, but you need cfm numbers to get a true idea. You want a cam with a wide centerline, say 112 or so, and that leans towards the exh a bit. Not too much overlap. That intake will hurt, because your ports are larger, and the intake's ports and plenum volume are still small. The exh manifolds arent bad. The carb will take some tuning, but it will work. In terms of FAST stuff, you need a MUCH larger engine..418 ish, plus having all the oither stuff max ported and/or extrude honed. And the carb professionally redone and setup...I'm assuming you meant in appearance only.
