Its a 97 ws6 lt1 heads and cam car made 410rwhp and it has a 9” rear end not bad for a lt1. I no theres more room to improve i had almost a full tank of gas and im going with skinnies next time.

That seems like a pretty low mph for that hp. For comparison my third gen trapped 121 with 407rwhp. But congrats on the time, you’ve got a lot more in it for sure with 410rwhp you can get into the 11’s. Also my lead sled gto at probably 3900lbs with me in it ran 12.10 @ 113. In crappy conditions like you ran. 1.73 60ft. The da was about 1200ft and the temp was over 90 and the humidity was at 43%

you can. But I’d be willing to bet your midrange part of your tune isn’t dialed in. You made good hp on the Dyno but you need the motor to make good power WHILE ITS PULLING. Not maybe people realize that and lay down big overall numbers but during the pull at the track the load is different and it’s not revving or accelerating through the rpm like it should. That’s how a lower hp car can beat a higher hp car if everything is close. It’s alot more to it than that but I’m short you may not have enough timing or fueling could be wrong down low. You have a lighter car than me. And making just as much or more power than me but trapping the same. So that tells me the midrange power is off.

Yep it's usually best to shift around 200-300 rpm after it peaks. Look at your dyno sheet and see where that is exactly. I'm thinking a little less than 6500 (more like 6200) but I can't say for sure since it's not my ride. Let us know how it works out. I think you'll be pleasantly surprised
