I say 3.4 all the way. Yeah you can put the 3.0 in there, in fact about a month ago I think I read a post on here from someone who did.(or the truck had it done when he got it, don't remember) However, for the expense and work put the 3.4 in, more bang for the buck.

I guess if you were in a situation where you had a donor truck and therefore access to the radiator, tranny, motor mounts, wiring, ECU, etc... and your 22re was blown, yeah that could be worth it. The 3.0 is a very tough engine. But otherwise, just search on 3.4 swap and see what you think.
