My 528 cube 3000 lb torqueflite car has power to run 8.80s. It had 50/50 weight distribution and the ladderbars could be dropped below the nuetral line by using the bottom hole. 24.5 tall goodyears up front, 33.5x15 stiff sidewalls in back. Launch rpm was 5000 throttle stop setting for quickest launch with a 6000 stall converter. Data logged. Grinner brake. I needed 1 .10 or more for a full tree and i consider my personal eeaction time to be .01 slower than a lot of guys . i hope this info helps.
If i moved the ladder bar up in front i would regain the rollout, pick up .02 et but at the cost of .02 slower reaction time.
