looking for engine computer 4379899 or possibly 4379923
the "899" supersedes to a reman; R4557391. these are both 89 Truck, 360, TBI, the "899" I guess is "std", 49-state" the '923 is "HD emissions" version. the current Cali-spec computer in the truck comes back as 89, 360,TBI, "HD" emissions I have reason to believe the computer is "bad" (going thru the flow chart) but now that the truck is NOT in Cali (and won't be again) I'd get a 49-state version as long as I gotta change the computer anyway.

"Plan-B" is to remove the TBI entirely and revert to a 4 barrel TQ-based carb conversion.
 
I have some new and rebuilt computers that came from a Dodge dealer that went out of business in the mid 90's. So far I haven't been able to figure out what they fit but I'll look through them and see if any of them are one of the numbers you mentioned and let you know tomorrow eve. I just want to clear some stuff out so if I have one the price will be quite reasonable.
