Response to 390 Test and Tune...

Stock crank with a .040 overbore. Car weight is 3220# including me. New tires are a M/T 28x10.5W which replaced the M/T 28x11.5's. So far, haven't seen anything other than consistency. I'll move the CalTrac bars and put my Goodyears back on for the next outing. They are taller so MPH should go up but the air conditions will likely be worse and it may be a wash.

Wheelie's are a random occurrence that seemed to have disappeared lately. Normally, a 1.42 60' would mean some decent air under the fronts but it now just drives away.

BTW.. that photo is a couple years old but I thought it was a cool shot with a bit of photo editing for effect.
