Hi Mike,

I didn't expect to find someone with the good taste to enjoy driving
full-sized Jeeps on this list :)

A friend of mine, Michael Baxter, is in the process of doing the same
thing that you're doing.  He was planning on using a GM ECU, but he may
use a Ford instead.  He is using a stock 4 BBL manifold and installing an
injecter in each port.  He is using an AMC 401, a TH700R4 4L80E
transmission.  He hangs out on the "Pheonix" FSJ (Full-Size Jeep) list. 
You might want to compare notes with him.  He is very knowledgable.

To subscribe to the list, send a letter to majordomo at digest.net and put
"subscribe fsj" in the body of the message.

Send messages to the list by sending to fsj at digest.net.

Regards,
Ray Drouillard
