Well right now I'm in the process or swapping the LIM gasket on my 96 3100. I decided that since I'm at it I might want to look into the 3400 manifolds. With all the clearance issues and EGR changes, are there any year 3400 manifolds that are a direct bolt on which require no modification? It's too cold to spend much time fooling around with rewiring or refitting. I thought there used to be a tread that had a good compatability list but I can't find anything.

You should have roller rockers so no clearance issues if you do.
97 3400 from a minivan will be threaded on the coolant pipe thing.
The UIM from the earlier years also have the same style EGR adapter, I think a 99 would work fine, if not, you are ODBII, and can use the vertical mount EGR like 2000+ on the 2000+ UIM, the connectors are the same...sigpic

oh yeah you want to use the LIM that match your year heads. So 96 style LIM gaskets... Of course you'll need 3400 uppers.sigpic New 2010 project (click image)

96-99 3400 UIM's from the minivans should fit. If i recall correctly they don't have the 3400 letters on the plenum. Check when Ben to see if he has one available that he could port for you.Comment
