Porsche built 25 917s for homologation in 1969. It won Le Mans in 1970 and 1971, only losing when the rules changed. The 917 still holds the Le Mans fastest lap record.
The new high-compression, overhead-valve, 303-cubic-inch Rocket V8 made up to 165 hp when the best Ford only made 100. The 88 was prototype for the next 25 years of American performance.
