I try to make my site as easy to understand and use as possible, but I realize there might be some beneficial changes. In other words, I'm fairly certain my site contains all the information you need, but I'm not at all certain I'm presenting it clearly.

Specifically, what do you mean by "practical diagrams"? Perhaps this is something that needs to be added.

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!

This is TREMENDOUS, guys !!
All the replies, covered EVERYTHING
I''ve got a new fuel pump / system coming in on Tuesday ( actaully dropped to zero fuel pressure at top of 1st and 2nd gear ! ).
During this time, I'll "adjust" the rear springs in order to get the rear ride height where it should be.

oh... Mike.... that was YOUR car ?????!!!!!!!
Got some photos of THAT one !
clutch pedal forever !

What is your pinion angle set at and what kind of bushings are you useing ?

Here's another web site that might help some

That was informative, Bud... informed me that ALL the factory mounting bracketes on the rear housing and the frame, are quite simply, fundamentally, in the wrong location !
Both upper and lower re BEHIND the axle centre... apparently counter-productive.

May have more of a problem than I thought.

Mike and Dwight, are you saying she needs to lower her IC and move it back? According to Baseline Suspensions, a higher and farther forward IC tends to plant the rear tires harder and lift the nose. Why would that be bad?
