The first video was my first pass with the 590 cam and the fourth pass with the 660's. So by the last pass on 11/21 (6 passes later)we were able to get the jetting and shift point adjusted to post the 10.75. When I finished that pass, I temped the tubes and had three 200* below the others and after I saw the video I could see the puffs of smoke at launch. The motor was pulled this past Friday and tore down, thus the purpose of the original post in that I wanted to know if trying to go 10.0's on an 8" rim and 10.5" tire was a bad plan.
