is the B30A block the Same as the B30E block? has any one had any experiance using the fuel injected "E" head in place of the carbureted "A" head? I was told that I could tap the injector holes and plug them and use my carbureted manifold on it. the injector holes should be under vacuum and should pose no problem, although with the larger valves in the injector head I should get a little more power even though it has carbureters. is this information correct?<br /> Also....does anyone know if the 270 chrysler outdrive had a tilt/trim option, rather than just tilt.
