Now that my '57 292 has been rebuilt (bored .040) and the original 2 barrel Holley has been replaced by a 4 barrel Autolite on a B manifold, I need to figure out what to do with the original dizzy (FEH 12127). Should I rebuild it or change it out with a later model?  I'd like to keep it as original as possible. I know the '57 and '58 used a ball bearing breaker plate and that in '59 they went to a hinged plate. Is there any advantage to these later versions?  Does the carburetor change make any difference?
