Guess what it'll run thread Long post incoming:
Considering hitting the track on the 25th(if I can get my ducks in a row) to get a base line for the car. My quest is for a 9.99(it won't run that yet) but have absolutely no clue where I stand currently. I'd be happy upper 11s first time out with this drivetrain.
Car: 75 camaro 3700lbs in current form
Engine:
Forged 370 LS with 9.6:1 compression
Lsa heads(rectangle port)
Btr stage 2 turbo cam(226/231 @0.050 113lsa 609/610 lift)
Lsa supercharger 2.45 upper stock lower(10.7-11psi of boost)
1 7/8 headers to 3" exhaust(xpipe with magna flow mufflers) dumped at the axle
Will be running an e85 mix(My guess and previous experience was about e55) I have my table set to add 2.5* of timing at e50 and 3.5* on e85.
Total timing: 13 on 93 with about 16 on e85--might play with this a bit. I am new to the boost game. I'm semi scared to go much higher but I'm no expert.
8hp70 transmission stock stall with transbrake(will try first and second gear launches)
3.00 rear gear ford 9"
note-- the 3.00 rear gears with the 8hp first gear is like a th400/th350 with 5.70 gears. The 3.00 rear gear with the 8hp 2nd gear is like a th400 or th350 with 3.80 gear
275/60-15 drag radials, little old(5 years or so)
Previous drivetrain:
11.3 at 122 with a 489/th400/3.73 3500 stall. On a draggy I did manage a 10.9@124 later, but I don't count that.(surprisingly it weighed exactly the same as it does now)

Lots of factors there and sounds like a fun car. That 8hp70 definitely sounds interesting as well, did you have to cut the tunnel up to make it fit? The stock converter sounds like it stalls up decently high, so hopefully that really won't lug you down terribly. Since the car seemed to work well before, I'm going to guess that you run a 10.5 @ 130, but I may be way off
