Hi everyone. I have a 1970 challenger rt se with a 383 bored 0.040 over, lunati 220/226 60302 cam, stealth heads shaved 0.040" kb400 pistons giving roughly 9.4:1, 770 and 750 holley vac and mech carbs available, stock HP manifolds with super turbos and stock exhaust piping, intake is dp4b. P/B and P/S, also have running a/c but having it work at idle is not a must.
Rest is 727 trans with stock histall vert (flashing 2600) , rear is 3.55SG with f70-14 (3000rpm at 62 mph). Car is numbers matching.
Car goes nice 5.6s 0-62mph, 13.9 best ET, 100mph trap speed. Problems with tracion in 1st, I have to take off at no more than 1200 rpm, shifting at 5100 rpm.

Question - if i wish to switch to a solid cam, lets say MP 528 BUT leaving everything as is (I have crane gold 1.6 rockers laying around) - will I gain anything or just choke the poor 383
I also considered comp xs268s but would like something less chebby... hughes solids are to long duration...

I read 528 goes well with manifolds but with more cubes than I have.

Anyone runs such combo with a 528 solid? I don't want to change the converter.

thanks
