Hey bjuice, the old motor was the 477. The 540 picked up everywhere. The 60' was 1.31 leaving at only 4200 where as my best before was 1.36. Lot more torque carried the front tires to about the 50' mark. Found out my jetting is really fat by 5 or 6 sizes so that will really pickup the MPH. The one good 90% pass as i was feeling out the car was 9.34 @ 141.99. I'm sure there is an easy 9.20's maybe more.
Tod i was shifting it at only 6800 since the motor was new. I'm going to try 7000 and 7200. Also i'm going to play with launch RPM and see what it likes. What do you shift your 540 at ?
