I was looking at a pic of a LS1 on Fquick, doing 1600RPMS at 60mph, with 4.10s

IF the tach is accurate and assuming 25.6" tall tire, its a 3.90.

I re ran the calculator, even with it being a 17, the side wall shrinks and the rim expands and the Overal Diameter is the same, on 3.90's its dead on @ 1800.

ASSUMING maybe a slipping clutch or a off tach it can be 3.42's due to it showing 1550/1600 is 70 mph.
