340 For street duty
I'm currently running a 340 w/ an old Torker intake, older holley 650 DP and 292/.508 hydraulic MP cam. It's plenty streetable and has just enough idle lope to it. I'd say my combo is good for about 350-375hp.
I have a new in the box Comp Magnum 270/470 cam (part#20-214-14) & lifters & rebuilt 650 double pumper that'd go well w/ your 2800stall and 3.55's. PM me if your interested. Bought it from an FABO member but have decided to stick with my cam. I'd let the cam/lifters go for $115 and carb for $100, that's what I paid.
