My best time with my bone stock motor'd LT4 was 12.74 at 107. I have a stack of 12.7x-12.9x timeslips. My best MPH was 109.9.
The car is VERY capable. With a decent driver and good traction, I suspect most would run a 13.00-13.50 depending on sea level. Better drivers will get it in the 12's.
[email protected] with my GS when it was bone stock, got it to trap 110mph a few times. Average times were 12.9-13.1 depending on weather and track conditions.
My LT-4 stock ran 13.3 108mph, 2.3 60's, the track where we go is poorly maintained and very old.
With the cam and head work, 13.1, 113mph same 60's but now it will spin through 2nd really bad, sideways bad.:laughing:
