All Mopar \6 Fuel Injection?

You guys are great! The Jeep manifolds look to be a different arrangement than the slant six, so the fuel rail would most likely be out. I pretty much expect to be doing-or having done-a decent amount of fabrication with the manifold and fuel rail.

Maybe the best way to choose a donor engine is to look at what tuners are available and go from there.

Bill, great points on making power with these engines. I'm not looking for a race engine, just really improved economy/efficiency and maybe a bit more power if it comes with the territory. If I wanted to up the output without getting too crazy, what's a fairly easily attainable target sticking with NA? 150-200hp with a PnP job, intake, exhaust and maybe a cam?

Careful selection of gear ratios would likely get the most drivability out of the engine too.
