I figure that there is someone on the forum that knows this. What is different between the 1995 and 1996 Chevrolet 4.3 V6 engines that they won't interchange?
My Nephew has a 94 Chevy truck with 4.3 and it has a problem, what I don't know. I found a 2008 4.3 V6 very cheap. I have been around Chevy engines all my life but haven't kept up on this particular issue. I am told that a 96 4.3 will not work on a 95 or older period. I don't understand this. If I take the intake and distributor from the 94 and put it on the later model it should work. I have been told by a dozen people that it won't work but no one can tell me why. I have been told that even a 1996 engine won't work in the 1994.
Any information will be most appreciated. I can make anything work in anything, but I don't want to get involved in something that is not worth the trouble of fooling with, especially if it is not mine. I will help him change the engine if it is pretty much plug and play.

Thanks, Ed
