Adding a positive displacement blower to that would make it even worse.
So....since I'm not building a drag truck and don't really need that hard hit down low...why not move the torque peak out as well as bring in the power a little slower?
I'm thinking stock heads and cam (for now, just to see how it works), a 6.1 intake manifold and an intercooled Procharger kit. Maybe ditching the P1SC and moving up a hair to the D1SC. The centrifigul won't hit as hard as the Magnuson and the 6.1 intake will be more of a mid-top end performer. Keep the stock 2600 stall but get a better converter anyway. The 4:10 gears will still give it plenty of go off the line but it'll really shine in the midrange which is honestly where we spend most of our time driving anyway.
I like the D1SC/6.1 intake idea with a MGH transmission. Nice linear power delivery that'll build as high as you wanna run the rpms. The P1SC would just hold you back once you want to turn it up some.
