4.0 to 4.0 ho please help!!!

Hello, I have an 88 Cherokee Laredo, and its got a bad engine. I know a guy who will sell me a 92' high output for $200.

Is it very straightforward swapping a 92' 4.0 HO for a 88 4.0?

use the block/internals from the HO. Slap the Renix on it, reflash the computer. good to go. I got way more power in my jeep which is like this compared to my friend's '92 Wrangler 4.0.

I got a '95 block and internals, according to the casting numbers, and diffidently renix control system.

good luck
