We take a glance at some of Ford's and GM's finest that raised the performance bar thanks to 427 power

FORD THUNDERBOLT
This factory dragstrip-special Fairlane Tudor was powered by a twin 4-bbl version of the 427 that insiders say produced close to 450kW max power.
1966
FORD GT40
In 1963 Henry Ford II contracted UK race car builder Eric Broadley of Lola Cars to build him a Ferrari-beating endurance racer. Early versions of the new Ford GT40 powered by Ford’s 289 V8 and then the 302 showed promise in competition in 1964-65. Then with Ford himself present at Le Mans in 1966, 427-powered . GT40s finished 1, 2, 3 in the 24-hour event. Job done!
