Well I've picked up a 2001 XJ 4.0 with a blown head gasket. But it has a nice interior, ford 88 rear end, fresh rebuilt stock up front, on top of a six inch lift. So my plans are to take the undercarriage/interior out of this one. What would you guys advise; repairing this newer motor/auto tranny setup and swapping that or use the running 4.0 in my 1989 XJ with the 5speed which hates gears 3 & 4.. And beyond that, where should I start? I'm literally going to strip everything I can down on the Comanche to get rid of any cancer I can of course but where should I start after that? Motor/tranny swap or axles/lift? Just trying to save myself some time :) Thank you for your time!
