Engine 84 CJ7 Engine Swap

[Bartman1959]

I'm looking at buying an 87 CJ7 with a blown engine. "Blown" as in a rod through the block, not an 871 blower. It had the AMC 258 i6 / 4.2l in it, but curious what other NON SBC Jeep options I have using the existing Transmission /Transfer Case . I would love to drop a AMC 304 in there, but not sure what that swap entails. Any guidance here would be greatly appreciated.

Not trying to hi jack the thread, just sharing info. TSB8C, I run a single Derale 18217 17" fan putting out 2400cfm on a 3-core aluminum rad. I'm running back and forth from Rio Grande City to Del Rio a lot. Never had an issue with over temp. Just remember by nature the LS engines like to run seemingly high around 200-210, at least in my experience. I also added a green LED in the dash so when the fan comes on, I know it is on. Too much money invested not to know for sure when it's on or not. Back to the regular scheduled show.
