No , not according to my Consumer Guide book . In a 1966 Ford Mustang there was the 200 cubic inch straight 6 cylinder and 3 different horsepower versions of the 289 V8 . They list a 390 option in the 1967 Mustang
It depends on what engine is in it and who's driving, my 1966 with a stock 289 has gone 130 mph.
I believe that is 3.68 inches for the 200 cubic inch straight 6 cylinder
