The 304 in my Jav came to me with a Mallory Dual Point unit (#2560001). The engine was rebuilt in the 80s, and was refitted with a midrange cam, Torker, and 625CFM Carter AFB. It's got minor issues, but it runs well enough to drive while I build up something with more (ahem) attitude. I really have no wish to mess with a Dual Point. It works OK, but doesn't have a vacuum advance, which (I think) is a problem for a street car. I can apparently retrofit it with electronic guts, but I can't add the vacuum advance. So, best thing may be just to replace it with something else. HEI seems like the simplest way to go, but I don't trust the quality of some of the stuff in the aftermarket. Just getting a rebuilt for some GM application seems easy enough to do, but I don't know what I don't know to make it fit. So, starting questions: * Any difference between 71 and 74? I see some AMC-specific parts that say 72-up. What could be the difference? I can't imagine why there'd be any mechanically. (Reason I ask is that the existing engine is a 71, but there's a 74 360 I'm working on to eventually take it's place). * Are there suggested GM target donors I should look at for compatible oil pump drive, rotation, length, etc?
