So a connecting rod pushed thru the oil pan of my '95 H.O. 4.0
last weekend mud boggin'. I have a 1987 comanche laredo 4.0.
My question: is the engine block/head compatible with my '95 cherokee?
I think the 87 comanche's motor is probably not the H.O. version as the
cherokee is the H.O. I'm just interested if the block/heads are inter-
changeable. I'm not concerned about a few horsepower. I imagine the
87 American motors truck has the Renix ignition and the 95 cherokee has
the updated Chrysler electronics. Anyone out there have experienced
regarding this motor comparability usage? -Bruski in NE lower pensula

Easy peasy.
