Bill ,thanks, I run a stock c/4 with a 3.20 gear, I think the car weighs in around 2,700 without driver. I have made a few passes untuned and went 10.57 at 61 M.P.H. in the 1/8th with a bit of wheel spin. not a barn burner but enough to have a little fun. The roadrunner had a fresh 318 with a RV cam, edelbrock intake and carb and full length headers.
