We're putting a Tbi 350 out of a
'89 700-R4 4x4 into a
'91 4.3 5 speed 4x4
and I'm trying to track down the right chip.
The 89 has the 1227747 computer but the 91 is missing that tag so i'm not sure which one it has. (may be a 16143900)

I know that the 1224747 ecm is the right box for a '91 V8 so can we take the computer from the V8 truck and put it in the 4.3 truck?
As long as we have a chip for a '89 350 5 speed it will work right???


i hate fuel injection.:rolleyes:
