My 72 Scamp has a 318, bored .030, 3 angle valve job, 4 barrel edelbrock carb and intake, and .454 lift comp cam. Exhaust manifolds. 7.25 rear with 2.76 gears and a 904 trans with 2800 stall and shift kit. I dyno'd 200 HP and 240 TQ. Ran 15.20s before the trans rebuild and stall. Runs 15.40s after the rebuild (even slower off the line with the stall, need some gears!).
Sometimes with more stall you shoot yourself in the foot.The trick is to match to peak torque not just say you need more stall. Chassis dynos are ok for tuning dont go by the numbers they will all dissapoint you.
