'98 Vortec 350 - Good swap into a Jeep?

[Ken Kelly]

Shannen,
Ward,
	I didn't realize the 98 Vortec was distributorless. That
would be a problem with compatablity in the old PCM's. I
would assume that running a 747 would require adding a
distributor or modifying the 747 Code. Do any of the 747
Proms support a distributorless engine?
