Hey guys, let me know your thoughts about my numbers. I know automatics dyno less than a manual, but how do the numbers seem to you? I have read that the stall will eat up about 20-30 hp on the dyno.

370 rwhp / 402 rwtq
No dyno sheet yet, was told numbers over text.

99 LS1
BTR Stage 3 cam Specs: 229/244 .630"/.615" 113+4
BTR valvetrain (Ti retainers, 0.645" springs, trunion upgrade, etc)
799 heads (not ported)
Vararam
ATI Super Damper underdrive pulley
Stock LS1 intake and exhaust
Yank SS3600 stall
3.15 gear


Next years plans are LS6 intake and headers / x pipe and full exhaust

Your exhaust manifolds are choking that cam. Get some good 1 7/8 headers and forget the ls6 intake, go with a fast 92/92 combo, and I’m guessing you should be at 420+ wheel horsepower.

im at 340 with just headers, intake, tune, through an auto trans, that was before I got 3.73 gears and 3200 converter.

How’s the drivability, sounds like you have the right converter, but no gear?

Good luck

I'm getting it back tomorrow. Wasn't gonna be an all out build. Started with just the balancer, then "while you're there" ...
I'm prob not gonna change gears at all. Gonna stick some drag radials under it and see what I can run it.
Any ideas on what you think it will run?

I’m curious to see what it runs with drag radials and that converter. My best so far on street tires is 12.5@111. 60 foot was 1.97. I can’t even load my 3200 converter at the line or I spin. I need drag radials just for a launch.

I don’t even want to guess what you would run. Have fun, go run it, and report back.
