So... the 3.0 in my 2007 is developing a pretty good knock. I'm going to try a couple of quick fixes (like thicker oil, etc) and see if it helps, but I've at least been tossing around the idea of swapping in the 4.0 OHV from my '99 into this truck as the 4.0 OHV still runs like a fricking champ.
Looking it over, it appears that the 4.0 OHV bolted up to the same M50D-R1 Manual transmission (even though my current one is bolted to the 4R55E Auto).
Will these just bolt up? Do I need any sort of adaptor or anything? Hopefully the answer is not and I can just pull the engine. Would make things a lot simpler (and a better possibility).
Information I pulled was from here:
Also, I should note that Minnesota doesn't do any sort of vehicle check where the engine has to be newer then the car so that's not a problem here.
