Sorry, I got so involved with uploading the picture I forgot to include some points that may help, what did and didn't improve performance:

2.14 & 1.81 valves: Heads pocket ported and ports cleaned up
950 Holly on M1 intake (I had a 800 dp Holley before- the 950 is faster)
Turbo Action "J" 5000 converter...works better than the 4000 Coan it used to have
4.30 spool (4.56 did not change performance)
Cal-Tracs helped the car hook and leave consistently

It seems to me your getting good performance from your car, but I know what you mean, it's time for a little more thrill.....
