The BT23F was a version of the popular BT23 F2 design built for SCCA Formula B in 1968 as an alternative to the F3-based BT21C. Only one was built, for Bill Gublemann, but two very similar cars were built with different gearboxes as the BT23G.

Like the Formula 2 BT23, the BT23F used the Hewland FT200 gearbox which was designed specifically for Cosworth's new FVA F2 engine. The otherwise identical BT23G used the older Hewland Mk 5 which had been designed in 1963 for the Lotus twin cam. The FT200 would have been slightly stronger and only slightly heavier and slightly more expensive.

All and any help would be gratefully received. Please email Allen at allen@oldracingcars.com if you can add anything.
