Thinking about trying a 4500 but would like some opinions here's my combo.

446Ci 440 10.5 compression Trick Flow 240 heads 267@ .050 solid flat tappet. Victor Intake and a 80496-1 950 hp that's had some work done by Thumper. Runs on 93 pump gas. The rest of the car is 8" 5800 converter 4.10 Dana (Originally was 4.30 8 3/4 but it broke) Car weighs 3470 now with me and last time out in pretty good air it went 10.39 @ 127
The 950 runs great and has awesome shift recovery so that and the car weight has me skeptical. Thoughts???
