What is the difference between the 97-90 4.0L and the 92+?

There is a local deal on a new ATK engine, I am looking at rebuilding mine but this deal is so damn tempting.
The new ATK would cost less than rebuilding my current 4.0L. Is it worth it? Will it work or should I just rebuild mine?

Thanks.

 

What years you want?(read your post lol)1987-90 I beleive are all renix engine's, 1991-1996 are ho engines , and 1997-2001 are(ho also) but renamed power tech.Yes an atk is worth it check out the prices on 4wd.com under 2000 bucks there.

 

Yea, I blew it on the OP. The engine is listed as a 1987-1990. Is there a physical difference between the renix and H.O.'s? Its a long block assembly curious if I could drop it in place and run all my accessories without issue.

 

Yes you can install it and run it. I've done 3 of them. Intake ports are off a bit. Use your flywheel, dizzy, manifolds and sensors. Treat it as a long block swap and you'll be fine. Be sure to use the HO intake/exhaust gasket.

 

Which dizzy? Camshaft or crankshaft?

 

I had to make a bracket for my coil and had to use the up right oil filter housing. 90 engine into a 93 just got the engine into the jeep yesterday.

 

I see the profits quickly eroding....

 

Dizzy = distributor. There's only one.
