What do you think it could run?

Should run 12-12.5 if its running good! I spend all my time on the 1/8 but I would expect that car to go 7.75 @ 88-90mph and drive it home. I have a 383 in my Super Bee that is comparable to yours has ran a best of 7.98 @ 86 with a 3500 converter and 3.55 gears w/28in radials that by the calculators is 12.40s 1/4. Long story short.... I'll race you.
