Cam and Stall Convertor
Turd, not my way with a good converter. You want it to run 12's, I'd suggest you buy a good converter. Who cares how it runs at idle-3K when you are racing with 4k+ converter.
I see there are "other" considerations now, future sale. IMO, you'll be very close to running 12's. The lighter the car, the better. Work on the 60'. It's good now, but still about .05-.10 light for your current ET. The converter will help here.
I see you made a choice. It will run good with that cam. My guess, tuned up right it will make about 310-320 corrected hp at the flywheel. A 360 with that cam, ld340, headers, 750dp making a corrected 345hp/400tq with a 2500 converter, 2.93 gears at 3250#, ran 14.15 at 103.5 with 2.2 60's in 4000ft air in Vegas. My guess it might have made 320hp in the air available.
Good luck.
