Hi, I know very little about automotive mechanics, but ive replaced the original 6 cylinder out of my 55 chev, with a GM crate engine. I think its what is referred to as their "HO" 350/350.
My question is I have no idea what sort of fuel pump I should be using for this engine.
Im not sure what size the carburettor is either...... I know its a Holley, but the place that sold me the engine suggested it was a 750, but all the press I've seen from the GM website says its gonna be a 600.
Either way, I need to know is the flow of the pump related to the size of the engiune/carb combination, and whether a carburetted car can use a electric pump, or it has to be mechanical...

Thanks :
