1970 12 Hours of Sebring

[1] With the 1969 to 1971 rules allowing sportscars with 5-litre-engines if at least 25 were made, which did Porsche early in 1969 with the Porsche 917 and Ferrari late in the year with the Ferrari 512S, up to 50 V12-powered race cars were available for the 1970 World Sportscar Championship endurance racing season, entered either by factory-backed teams, or by independent customers if they could find funding and pilots that could handle a 500+ hp car competitively for at least six hours, or up to 24h in some events.

John Wyer's Gulf-Porsche team had just come fresh off a 1-2 victory at the 1970 24 Hours of Daytona 7 weeks earlier.

There was an accident between two Lolas- Bob Brown in the #26 car would continue, but Mike De Udy in the other Lola would retire after just one lap.

And running in 5th place was a Solar Productions/Gulf sponsored #48 Porsche 908/02 of movie star and racer Steve McQueen (whose leg was in a cast) and Peter Revson, who was battling with the #33 works Alfa Romeo T33/3 of Toine Hezemans/Masten Gregory.

Although the #21 car was a lap behind; Andretti went out, and pushed very hard; unlapped himself and was making up time quickly on Siffert and Revson.

But then all of a sudden, Siffert brought the #15 Gulf-Porsche 917K into the pits with front hub failure, the same problems which had stricken its sister car.

This long pitstop allowed the Solar Productions Porsche 908/02 to take 1st- but Andretti had managed to pass Revson and take the lead back.
