(first posted 3/28/2018) Let’s face it; the original Mustang was never really well-suited for big block engines. The 390 in the 1967-1968 generation was widely panned for its atrocious handling. And then adding another 3.8″ inches of front overhang to the restyled 1969 version was only going to make things worse. The 428 didn’t really weigh anymore than the 390, but combined with the heavy C6 automatic, power steering and an oil cooler, the Mach 1 weighed in with 59.3% of its weight over the front wheels. Is that a record for front-engine RWD cars?
Needless to say, handling suffered, as well as traction.
