i've already got the head and exhaust picked up, got them off someone's 4.0 for $100 altogether. i dropped it off at the machine shop a d they found one crack in the valve seat of one of the cylinders...it isn't leaking anything, but it still makes me a little nervous. i went ahead and threw in some new lifters since it looks like the swap is on hold for a bit. i did the 2150 +tfi/whatever you want to call it already so i'll be running better in the meantime. thank you all for the suggestions and advice

whoops, meant cherokee etc...just listed in the same engine manual.

might be a dumb question, but is there enough room to remove the cam without pulling the engine?

Sorry to resurrect an old thread, but just wanted to make sure it was on record that you can remove the cam without pulling the engine.

yes, pull the head and lifters. also need to pull radiator and ac condenser if you have it, then timing set etc. can pull can through the front end where radiator was before, just be careful not to bang the cam up when removing and reinstalling

Also the 4.0 cam has no fuel pump lobe so you would need to go with an electric fuel pump. I think you could find an aftermarket 4.2 cam with similar statistics to the 4.0 cam if you are running a carb.

I went with this one, not a real radical cam but an upgrade from stock and still has the fuel pump lobe.
