ja Wittman käytti roverin 215L kasia myös lentokone käytössä.

Another Wittman mod utilized the little 215-inch aluminum engine V8’s that were used in Oldsmobile F-85s of the early 1960s, Wittman side-stepped the usual gearbox, which designers utilize auto conversions to keep the engine turning fast and the prop turning slow. Instead, he turned the engine backwards and put the fly wheel in front, bolted on an extension and prop. and simply let the unit turn as fast as he thought it could without driving the tips supersonic. Utilizing his own propeller design, he felt he was able to pull an honest 155-160 horsepower with no major modifications to the engine other than replacing the original 215 crank with the longer stroke 300-inch unit. From the outside, you would never know it was a liquid-cooled engine, since he kept the radiator entirely within the engine cowling where it cooled beautifully. Although only a small number of aircraft have been built using that engine, they have. almost without exception, performed flawlessly.

sa (sai optiona myös Pontiac tempestiin), missä kyseinen 215 kuutiotuumainen alumiininen V8 nähtiin ensimmäistä kertaa ja vuotta myöhemmin esiteltiin tuossa jutussa ollut turbo-versio tuohon Oldsin jetfiren
) vaan menosuuntaan nähden takaperin, niin että potkurinakseli oli kiinnitetty vauhtipyörään.
