Call FPP's Ron Miller.
He knows a guy in Arizona who can make one for you.
Here's what you tell Ron:
"I have a Mickey Thompson FE crossram. I need an extension for the distributor drive."
When you get the guy's number, I lost it, you just tell him what you need and he'll send it to you. A hundred bucks if I remember right. Just tell him what you want: a stub drive for the distributor hole to drive the
oil pump.
Dropped right in, no problems.
Your other option is an external
oil pump, MOPAR hemis have several versions available for them that can be fairly easily adapted to the FE...this is for an external
oil pump, not a dry sump system.
