engine swap

Doing a UCF skid with my engine swap and even after pushing the 5.9 as far back as possible to weld the engine mounts in I knew the trans was still about 2" further forward than the factory position. On the upside, that means I get a little more rear drive shaft length which I'll be needing due...

I know this isn't exactly a straight-forward answer, there's a lot that goes into it. So, I'll start with the basics and you guys can give me feedback and I can fill in the gaps on anything I didn't specify initially. My Magnum V8 swap is nearing an end. The past 2 days have been spent...

I'm sure this has been covered before ,but since I can't find a good direct explanation I'm going to ask it. I need to swap out my 4.0 from my 97 Wrangler, and found a 4.0 from a 97 xj I think should work, if I am reading this thread...

I have a 98 tj that I have had since college. It is the 4 banger AND it is automatic, so it is basically gutless.

Is there a way to get the check engine light to rest/turn off/disable after swapping an engine out? I am looking at a 99 TJ that had an engine from a 2000 Cherokee (Inline6) and the owner is telling me that is why the check engine light is on. Rig seems to run just fine. The problem is VA will...

Looking for a engine builder in Ga. Atlanta area. Have a 97 TJ needs a motor. Has a 2.5 want to replace it with 4.0

OK, so I ripped out the exhaust (and intake) manifold and put back in with a new felpro gasket to see if an exhaust leak was the cause of the nasty ticking noise in my new-to-me 2001 4.0L. Nope, not the prob. It's a main bearing or lifter rod or collapsed lifter, or gremlin poo (or, whatever)...

Looking for advice, tips, and hints on swapping out my I6 engine Things to think about prior to taking out engine, extra parts to have around, or things to do on new engine that is getting swapped out with old one.
