ECM part numbers?

[Mike Rolica]

I think it is becaue of the diff between motors..
Some diff.. the 4.3 have  2 hegos the 305 and 350 have 1... some seem to
have hegos and some don't from the same year and motor.....
May have to with 4x4... have a guy here at  work who put a 350 in a 4.3 fs
(95).. we used the chip from the 95 fschev and it worked.. even though they
have diff ecm's...some of the pins between ecms were different though..

		I've *heard* that the bins from any of these interchange and
work just fine
		in any of the ecms mentioned.  Why all the different numbers
I haven't a
		clue.
