LOL, how old are you, that was not available in a 66. You could get it with a 390. Still would not run 140. Possible speed with no wind resistance is rpm of engine and diameter of tire, computed by rear end ratio. My 273 valiant would run 115 in third gear, and about 125 in fourth, but a few of those and a new clutch was needed. My 66 plymouth 383 would run about 106 to 110, 390 rear end. My sisters fury II, va police interceptor, 440 would top out about 135.

I looked it up and the 427 did not come out in Cyclones until ‘68. I figured with the T-Bolt getting it earlier, it would have also made it to the Cyclone.

I guess the closest I am going to get to that is the ‘67 Fairlane GTA S code sitting in the shop awaiting restoration. Someday...

I am surprised the 440 Fury Interceptor was not faster judging on some threads contributed to by former California HP officers.

I cannot imagine running that speed on bias ply tires and maybe front drum brakes.
