My only problem is with the 8BA distributors. They were vacuum only advance with no centrifugal. This makes them a no advance at all distributor in this application. They will have to be run at full advance all the time like an airplane engine. Airplane engines use either an electronic shower of sparks starting aid system or an impulse coupling to retard the spark but neither would be practical for street use. Those old Scintilla Vertex mags take a good bit of power to turn them but at least it would have some form of centrifugal advance.
