New best with my Trans am
I went to the track sunday with my trans am that has not been raced in a couple years . I built another car(64 Nova) so that i would not beat on this one anymore. THe last engine which was a stock ls1 shortbolck with ported ls1 heads with 2.02 , 1.55 valves and mildly ported (flow 262 int-220 exh) and an f13 cam went 11.38@121.3 mph in race trim with skinny's and 275x50x15 m/t drag radials with 1.59 60ft.
I now have a lq4 short block with same heads and swapped the f13 for an f14cam.
At 3850 with me in it On 315x35x17 Nittos the car went 11.32@121.39 with 1.665 60 . I was stoked, full street trim exept open cutout and a new best.

Yes m6 running 4.11 gears and I left at 5200 on that pass.my clutch is a spec stage 3+ and it's on it's last leg so it worked great with the nitto's . Did not shock them or bog,just left nice. I am going to tune it on the dyno at engine power systems Thursday and guessing around 460 at the wheels.
The ls1 block did 441/410 and this engine makes more mph.
I think tuning will gain a few but not much. I street tuned it with efi live.

My SS runs similar mph but no where close to your et. On my first ever 4k launch, my new Mcleod clutch let go . I figured my car should run around 11.3s with a decent launch, it's nice to see someone actually do it with similar mods. Now I have an idea what it's gonna take.

Stock shocks, Lakewood lca's,bmr adjustable Tq arm and deleted front sway bar. As for launching, I left as hard as it would allow , my clutch slipped itself out. If that were a fresh spec 3+ it would hit the tires and I leave hard still but don't hot re gas until it hits the tires and just starts to bog. Then I floor it.
