2.8 v6 to 3.4 v6 swap questions


Recommended Posts

I just bought a solid 1986 2.8 Comanche 4wd 5speed long bed, that has a bad engine, for $125. I am wondering about the 3.4 swap. Is it a direct bolt in with just the transfer of parts including acessories, fuel induction, sensors, etc??? Just wondering if I should try to fix this or just use it for parts for my '87. :help: Any help is greatly appreciated.

To do it as a drop-in, you basically have to strip the 3.4 and use the Jeep manifolds and carburetor. You get a nicer, more powerful and more economical engine if you retain the GM fuel injection, but that means some work in getting it all hooked up.

 

Either way, you have to use the Jeep flywheel and have it neutral balanced to work with the 3.4 engine.
