some years ago, the Late Bob Olthoff told me that the top end of the SPF cars he was producing then, with usually the 351-392 Windsor motors, with about 425-475 hp would go about 155 top end. This was with the then standard five speed overdrive Tremec running the customary 3.77 diff spinning 15 inch wheels.

With this gearing and a 392 motor, i have done 149 at the standing mile, still accelerating at the traps. With my present engine and gearing, i suspect i would go just under 160, max.

Unless one takes off the windscreen, and has a really big motor, i personally doubt the claims for speeds much over 160 mph.

all the best...
