10.5's with the 3:08 rear and low 10's with the 4:10 gear...just got a call from my engine builder that my motor is done..had old one freshened and changed the cam, and had 3/8" taken out of each intake runner. Old cam specs .667 lift and 264 duration at 50 on a 108 degree centerline New specs .667 lift and 291 duration at 50 on 107 degree centerline I was looking to move the power band down a little and get more power. New cam picks up 30 horse and 35 lbs of torque at 2000 rpm and gives me a little wider power band Have to wait to get back to the track and see what difference it made...old shift point was 7200 with a 8200 redline....
