I did it! I know it should ET better but I just wanted to at least go 120 this year and I did it. Combo in sig. 25psi and a little more than that with the converter locked. I even made it to the finals in a 26 car field and then spun off the line and couldn't run the other guy down. He was impressed that my mid 11, 120mph Buick got over 20mpg's though. Especially compared to his 502 chevelle that he drove in and was happy with a little over 10mpg's. And he was going 11.90's @112ish I think? I love beating up on big blocks. He had a beautiful car though. I'll try to post the go pro vid later.
