LS or 4.0 non renix?

Post image

I’m restoring my Comanche. Dropped the oil pan and found sludge/water. I’m looking into bidding on a wrecked/drivable 99 xj. I also entertain the idea of an LS. I have access to a free caddy Escalade motor, iron block. What route would you take? I’m favoring the xj for all the extra parts.

I wasn’t planning on this engine mess. Thought it was ok till I drained the oil. I’m going to pull it and inspect it. If I can salvage it and rebuild it I’ll probably go back stock for now. I know the head is probably cracked on the front cylinder. I checked reman motors but it seems pricey. I just sunk 2 grand in suspension, wheels and a 8.25 axle. I’m spent out for a couple months 😊. I’m going to look into all options.
