well i got to the track tonight on the fresh motor. i only have around 350 miles total on the motor. we are up here at 3500 ft. and a horrible density altitude, and a slick as hell track. my best 60 ft was a 2.5, which i know is horrible. i will try and get that down. my best ET was a 16.4 at 84 mph. i have no clue why it its so slow but im thinking maybe the new engine might have something to do with it, like mabey being tight???? well i dont know. anyone have any good suggestions for breaking in the engine?
