Supercharged 6.4L in a 64 Valiant

Is the EPSU a modified OEM unit, or aftermarket?
I just purchased one for a Saturn Vue, that should work well.

Aftermarket. Unisteer. From everything I've read, Saturn is the way to go if you want to piece it together yourself. There's a great thread on a Ford Falcon (TFFN) site I'm on. Someone did it for $100.
