Lower mount at frame... 12.125"
Upper mount at frame... 19"

I agree with Mike wholeheartedly. When I first read your post, the difference in measurements of the upper and lower bars jumped out at me. The upper bar is almost flat and the lower bar is pointed "uphill", so to speak. You will never make that work. The lower bar needs to be at least parallel to the ground, preferably pointed "downhill" from the axle like Mike said. The upper bar should be pointing downhill a lot.

You may need some work with the clutch settings, too. You have been given some good suggestions in the other posts, so I won't add anything else.

Once you get past these two areas, you will find some improved ET performance with lower trans gears. Be thinking in the range of 3.15 - 2.00 - 1.40 for the weight you are carrying. ET will be made in the first 330 feet; from that point on you are mainly carrying the weight.

Good luck and don't get discouraged! You have such a neat car and I applaud you for the resolve to crank it up!
