Nice update. That mph makes much more sense now. I had a 233/239 TSP cam in my Trans Am with stock LS1 heads and basically all the same bolt-ons as you and ran 399 RWHP and like 360RWTQ (was very lean at that time). After adding UD pulley, Fast 90/90 and better tuning it put down 427/380

Yea, I think the stock clutch may have been slipping just a tad also.

Hey Don...just so you know, my stock, best run was a 12.5 (don't remember the mph). I Installed a small reverse split 224 cam and AFR heads, headers, & ET Streets and dropped to a 11.33 @ 124 mph, thru the stock gear and mufflers. You will love the heads..trust me. That was 433 rwhp and 401 Tq. More cam would have really made a difference. Here is a sound clip of the cam....great street cam.

Here is the vid...embarassing shifting because of a crap RPS clutch but here you go anyway.
