8. Ford Mustang Boss SVT 429 10-liter
In 1969, Ford introduced the Boss 429 Mustang with a big, specially-built 7.0-liter semi-Hemi engine they designed for NASCAR. The engine had a 335 HP rating, but in fact, it delivered over 500 HP at high revs. Even though the Boss 429 was a sales flop only built as a homologation special, the legend survived. In the early 90’s, the engineers at Ford decided to build a one-off Mustang Boss 429 as a tribute to the legendary late 60’s muscle car.
Their idea was to take the new 1994 Mustang and old Boss 429 engine. They bored and stroked it up to 10 liters of displacement and married the two together. This created a Mustang with the biggest engine displacement in history and, as it turned out, the best 0 to 60 acceleration time.
With the rest of mechanics closer to a top fuel drag racer rather than a regular Mustang, the SVT Boss 429 delivered 855 HP. Astonishingly, it could run from 0 to 60 in 1.90 seconds flat.
