Re: 4 Cylinder Engines in CJ7
Maybe I'm misremembering but I seem to recall they needed a new 4cyl
engine and took the old six, removed two cylinders and redesigned the
head for better flow. The then took the "new" 4cyl engine and added two
cylinders to make the 4.0. For what it's worth both engines use the
same replacement pistons.
(Autozone says a Badger P830-20 for a .020 oversize piston for either
engine).

Whatever, Just so long as you know it was originally a 1926 Nash
engine:

They just added a water pump and filter.

Re: 4 Cylinder Engines in CJ7
The Cherokee got these engines first, then the Wranglers got them. Afaik,
none of them made it into CJs. I have the 4 cylinder engine in my Wrangler,
and no speeding tickets so far. ;^)
