135 140 yup
145 prolly not
ive been 6100 in drive with a 27 inch tire and 3.23s with a built 340 and nitrous i had plenty of motor left

Mine was NOT a 73 car or motor or 4000lbs. It was a 68 formula S 4 speed with 27+ inch tires 3.23 gears and still pulling at over 6500 rpm. And the tach checked good to my Snap-on meter. You figure it out. Or are you math limited too. :poke:
