The factory 7qt replica replacement sold through Mancini and Hughes, etc, with a Milodon windage tray. The factory type pan made by Milodon is a great choice as well. The Milodon circle track pan is the best option, IMO, but considerably more $$$.

The Performer RPM would be a great choice for intake if carbureted or TBI. The obsolete Mopar M1 single plain would be my first choice if you can find it.

Hedman makes shorty headers that fit well and are easy to install. 78073 or 78076 depending on coating. I'm unsure as to the fit with Source stealth heads.

A recurved dizzy from FBO or Firecore would be a suitable ignition. MSD works well, but may be more than necessary.

Go fuel injection. It's not much more $$ and it'll drive better all around.

Best of luck.
