I'd think you'd be in the 12's, with every thing working such as traction, gearing ect. Might even be better.

Altitude is a big factor. Where I live at 6000ft it would be mid/high 15's.Sea level 12's depending on your rear end gearing.

Yes way! Cant find the formula right now but its about 4-5%HP loss per 1000 ft in elevation.

3.55 gears, good tires, I'm thinking low 12's, middle 11's if I can get hp over 400 at wheels, I'm at 900ft above sea level

Only one real way to find out.

My 76 vette with 468 BBC maxing 520 hp at crank, th350, 3.36 gears, 3200 stall ran 11.60s to 11.80s.

I would think you would run low 12s, just a guess.

Probably 50 ft above sea level.

Take her to the track and let us know.

My 383 with 373 rwhp ran 11.62 in the 1/4 mile. I had a 3000 stall converter, Turbo 400, shift kit, and 4.11 gears.
