Hi, we are running a the 1.80 straight cut gear in our glide,with 4.30 gears and 315/60/15 drag radials. Leavin off the two step at 4200 rpm,and ran 1.37 60ft with a basic 383 sbc with an F-1R Procharger,nothing special,just out of the box AFR 227 heads, a Steve Morris solid roller,and Pro-Systems blowthrough carb.
For next year we will have a little wilder combination,a tall deck 434 sbc with 18* heads,F-1R Procharger,and alot of other changes,so we are thinking of changing the rear gears to something in the 3.50 range.
