Default ran at the track

first time at the track
256 rwhp 291 tq
made 15 runs in 4.5 hrs

best time 14.06
best mph 103.67
best rt .058
best 60' 2.047

this was on stock (for vettes) runflats sized 275 40 17

i really really think that my gears are killing me (2.73), last few car lengths of the track the car is busy shifting into third. I also think that they are making me not see the full potential of my 3200 stall.

what do you think that my car will hit with a gear change to 3.73's? 13.5's?

mods are built trans lm1 exhaust and tuning

Yep. Let me know when you get to 170K on the motor. Then add a TH400, 12 bolt and a Dennys Nitrous ready DS (Steel) and get back to me with track times.

The RRs and the EWP help, I am completely stock internally and run a stock WP. 110 is a pretty good trap speed for a stock internal LT1. Almost too good.
