Stock magnum heads cam roll call!

I got the 380 hp create with 727 and 2800 stall and 2.94 rear gears cam is around 288/296 .500 ish lift. Its pretty soft under 2000 rpm, have to drive in 2nd in town, and have to get her up to 40 mph in 1st before gasing it to feel its real power. Obviously a set of 4.10-4.30 would cure that. Even 3.55 would go a long way. My plans are to swap the single plane M1 intake for an airgap apparently worth 30 ish lbs-ft across the torque band. And add a set of Rhoads lifters then probably a set of 3.55 depending how much the intake and lifters help.
