Yep 6>6500rpm with slip although I doubt you'll get too much with that converter.
At a guessing weight of 3400lbs@the line and an honest 450fwhp/28" tyre your ticket could look like this if it hooks good>

60 Foot E.T. : 1.59 Seconds
1/8 Mile E.T. : 7.21 Seconds
1/8 Mile Trap Speed :94.25MPH
1/4 Mile E.T. : 11.43Seconds
1/4 Mile Trap Speed :117MPH
1/4 Mile Trap RPM :6054RPM+slip and with 4.10's 5772+

We got a street/strip Demon here with a mild 340/416 running 11.2's/118+ with similar hp, .500" hyd. cam, stock J heads, TR with 2 x 650DP's, Hughes 3500stall, SS springs, 3.91's/10x28's at approx 3250lbs, shifts@5500 traps@6000-ish.
