Mid to low 12's IF set up properly,13.00's to 14 if not. The gto I race runs 11.70-11.80 with 330 hp at the tires,figure driveline robs 80-100 hp between the th-400 and 12 bolt rearend so it has around 400 to 425 hp at the crank but weighs a little less than a street chevelle and isn't turning any accesories,Smitty

I'll say mid 13. This is a heavy car and 3.73 are good for street but not enough for the track, the engine won't be able to give his all on quarter mile. Trial it and then consider 4.10 or maybe even 4.56 depending on traction.

Going by memory................
Most average cars I saw run with that same engine build was mid to high 12's.
Older Camaro with 4 speed, 4:10's and 10.5 M&H's ran 12.0's
70' Nova with six point cage, no rear seat, fiberglass hood, 4:10's, 10.5 M&H's, 3800-3900 stall ran high 11's. I forget weight but was very light. Driver was maybe 160lbs soaking wet.
We race near sea level.
Anyway, converter, gear, tire, frt and rear suspensions mods, and WEIGHT have as much to do with it as HP, maybe even more so.
BTW: Don't necessarily go by the stall I mentioned. We played with converters on each car trying to hook up on the street and such. $600-$900 a converter was typical for us, even with the milder motors.
Exhaust was always 3" mandrel bent with either Dynomax Super Turbo's (stealth) or Flowmaster's (loud)
Get it out and run it. Then do some tweaks and run it again. The name of the game is besting your ET's as time goes on, that's the fun. You'll always be beat by some other cars.
Solid or boxed adjustable rear trailing arms help. Get that pinion angle correct !!!! Coil springs, rear sway bar, maybe even a air bag for rear, etc,etc,etc.
All depends on where you want to go. It's just as endless as boats.
