US Formula B 1970
The 1969 champion Mike Eyerly stayed in FB for 1970 and this time completely dominated the season with eight wins and three second places from 13 races in Fred Opert's Chevron B17B. Allan Lader, in an Opert-run Brabham BT29 was equally far ahead of the rest with two wins to add to the five times that he finished second to Eyerly.
Third was Jacques Couture in the mysterious Lotus "69B" that does not appear in Lotus records and may be a F2-style upgrade to his Lotus 59B. He recorded two back-to-back wins in the summer but retired too often to be a contender for overall honours.
The Chevron B17B and Lotus 69B were almost one-offs in the series with most drivers opting for the proven Brabham BT29. Future SCCA boss Nick Craw was fourth in the series in another Opert BT29 and Matt Spitzley was fifth in his private version. Three of the seven SCCA Divisions (see right) were also won by BT29s.

Brian Nelson, visiting from Northern Ireland in the Crosslé 18F, won the other race the season finale at Sebring in October. A big non-championship event at Road America in August was also won by the unstoppable Eyerly.
Fred Opert regarded Eyerly as one of the best drivers he ever worked with but his career floundered when he went to the 1971 Tasman series with a badly-prepared Surtees TS8 F5000 car and ran out of finance. He only raced a few more times in FB.
