Sorry, i wouldnt want to guess, but it sure sounds like a fun ride . Have fun!
I had to guess at the cam (my dyno asks for valve events, not duration) and also the exhuast (I went with small tube and mufflers). This is what I got: 414 hp @ 5440 and 439 tq @ 4480

I would guess high 11's with slicks <---just a guess!!!

My dyno program gets 394 HP and 369 TQ. These numbers are low for what you could get just by going to a little bit bigger cam (400's like to breath) and replacing the Torker II with a Victor Jr.

For et I get 11.79 @ 114 for the 1/4 mile
