Hello,
My 2.8lt recently went. I am gonna out a 3.4lt in it for now untill I can afford a 350. But I can find all the steps on doing the motor swap. But I was wondering. What parts will work from my 2.8 on the 3.4 and what will I have to go get for the 3.4 that my 2.8 wont support. I can only find partial list.

 

the easiest way to do this is strip the 3.4L down to a short block, then use all of your 2.8L accessories ontop of the 3.4L engine. so, you're intake manifold and engine accessories, sensors, etc. I would however retain the 3.4L's fuel injectors as they'll flow more than ur 2.8s, also i'd recommend buying the whole 3.4L engine, and selling off the components you won't need , it's intake and everything else. You could do a complete swap, but then it's not nearly as easy as it could be. Search for Ked85's articles the 3.4 swap boogie , and others, he's done 2 3.4L swaps and could help you find wha'ts needed....P.S. he hangs on the v6 board.
