Despite some teething pains, I managed a couple of 12.7's last night. I was pretty cautious only having put about 50 miles on the new engine. Starting from scratch once again w. air pressures/launch RPM/shift points/jetting/timing etc etc. The air temps were beyond belief. Wearing a helmet, long pants and the windows/doors shut..argh! Let's see how long until I'm bumped down the AC TOP 20 list.. BTW, James; 12.738 @ 104.57
