What parts from la 318?

The timing cover for LA engines will fit on a 5.2 (318) or 5.9 (360) Magnums, and then the accessories can be used from the LA donor. If you are planning on using a stock Magnum engine with a mechanical fuel pump, you will need a fuel pump eccentric adapter for the camshaft, available from Hughes Engines. Oil pan and oil pump pick up will be LA style, although I am not sure which pans fit a 63 Dart.

That fuel pump nose adapter from Hughes is an abortion... I had to re-engineer it when they sent me the wrong camshaft with that band-aid... I wanted the correct cam with the nose incorporated in it... No, they send me the magnum cam without the nose and add another $30 for that adapter kit to pump up their sale....

I modified a key way to replace that cheap *** chunk of aluminum that is supposed to clock the fuel pump eccentric...
