LS1/4L60E continues to impress
2nd to last race day at the track Saturday, cool relatively dry air. DA ~7500', 16 MPH head wind, 3480 lbs according to the track scale, it pulls off a 12.889 @ 106.60 MPH. Not sure where that came from, it was bracketed by 12.97 runs with basically the same weather conditions.
Really good news is the 60' times were more consistent today, which made 1/4 mile ET more consistent, which made it possible to actually guess at a dial-in.
According to those old internet HP calculators, that equates to about 325 HP at the wheels, 400+ at the flywheel. At altitude. No correction factors applied.

What are your mods on that car again? Just an LS6 intake, stall and the SSW Headers?

3.73 gears.
And shaved 317 heads, a free-flowing air inlet, 28 lb injectors that came with the LS6 intake. Single 3" exhaust with Magnaflow single in/out muffler. 3000 stall (seems like it wants more).
