You’re good to go John. I’ve done those years. The electronics don’t care about removing and installing the same type engine.
Its only installing different engines that cant be done. Like Huck’s EZ30 into an XT6, that’s no longer possible starting in 2005+.
You can swap the long block and retain original existing intake manifold if there are any small differences of the intake hose, vacuum or brackets, etc.
I’ve seen how your cars are kept, I’d want to keep that engine! I’m sure you took care of it, and that’s a good motor. It is a lot of parts but it’s not hard to do the rear cover.
The only tricky part is running the long bead of sealant, placing the orings, and setting the cover in place without disturbing the bead and orings. A helper would be useful but I’ve only done it myself, so it’s totally doable.
Ive got one of those engines and a new set of headgaskets to put on it but it had blown gaskets when I got the car so I wouldn’t want to send it your way.
But I might have some extra parts if you need any.
