30 inch tall tires so about 3300 rpm at 55 mph.It'll go faster but the 2100 pound narrow vehicle gets a bit dangerous .The 153 looks factory and besides more power than the Go Devil it get better fuel mileage. I lost of lot of photos when the hosting site went belly up



And how to make an 1986 S10 151 rear sump oil pan fit on a 153 . Resize the rear main cutout and some hammer clearance where the oil pump is.And it doesn't leak
