My XJ is a 5-spd manual; does that have any impact when replacing the 4.0L engine?

Thanks / appreciate.

I don't think so. The 4.0L has amazing longevity. Not unusual to go 350K

If you replace the engine with a different year you might need a different Pilot bearing. When I stroked mine and put in a 258 crank, the hole for the Pilot bearing was different in the end of the crankshaft.
