Guys, notice he is running only a 28" tire so he isn't too far off on gearing and converter.

When I had a home ported stock headed 408, .540 flat solid, 950hp carb, 4.56 gear, 30" tire, 4000 stall, 3500 lbs, I went 11.20 at 119.

He should be all over 10.7's.

But, with a little more gear and converter, easy mid 10's.
