I think you might be right about making to large of a move. I checked possible ICs again and I think I will try 39.85 and 8.375 first. Have checked tire guage. Running Hoosier C07 with about 100 runs on them. On our dragster they have been good to at least 225-250 runs in our experience. Kinda slow dragster 5.29 @130. Shocks are on the softest setting, (single adj. QA1s). I will try a lower air pressure also.
At 8000' I'm not sure my little motor would get out of the 8s. :lol: Is your car a chassis car? I don't get much front end travel compared to the travel of a back halve car (pinto front).
It does help having someone to bounce ideas off of, thanks Johnny.
