This is what it ran , how much is left in it

Agree with this..my duster with the 360 60' in the 1.65 range..with my 416 low 1.40's..what air pressure are you running??

yea my stock stroke 360 went 1.63 60' with a 3:91 gear and 26" tires.. with worn out 6 cyl leafs, 318 torsion bars and air shocks in the rear it still went a 1.69 60'

shifted at 5900 and went through the traps at like 6100. best time was a 12.17 at 108.9 mph. that was only like 350 hp at the wheels if i remember the math properly.
