I'm running an MSD pro billet dissy with MSD 6AL control box and want to fit tacho (probably moon/Sunpro or similar). Have read confilcting info, some saying that you do have to use a tach adapter and some saying its not neccesary, anyone got any advice? if I do need an adapter, which one? or is it worth getting tach first and just wiring it normally and see what happens?
Also what would be the maximum revs you can run a standard 350 SBC up to (1980 engine from a motorcaravan) ??
