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

70 should be 2k in 6th with 4.10's. 80 at 2200 rpm.

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

if you give us your tire size xxx/xx/xx we can tell you assuming your tach is dead accurate....which it probably isnt.

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.

im not encouraging you to speed, but if you know what rpm and gear your in at...say 120 mph will those same tires/wheels it will be more accurate.
