Engine Replacement for Willys

I have a 53 WillysOverland Jeep that I restored. My grand dad had it since 55 and handed it down to me a few years ago. I completly finished the body and right now Im working on the interior.

Its a great rig! But it has it the origional pea-shooter F134 engine, it may have been useful at it's time. It goes way too slow and has no horsepower (but then again all you guys who know your Willys know that), plus I get about 10mpg! Damn I can get just the same milage with a V8 with real horsepower. And my rig is a 4 banger!

So my question is what would you guys reccomend? I'm thinking about putting in a V6 or something. As much as I'd like to fit in a Chevy 350 I would probably have to replace a ton of other parts and turn the thing into a chevy.

Any suggestions?

If your not looking to do too much, I'd try a more modern 4 cyl. Any V6 or 8 is going to require a lot of work, Such as regearing and possible axle upgrades. I think an Iron duke would work OK, since it isn't that heavy.

Buick 225s and 231s are popular swaps into flatfenders. just estimating here but the 225s were used in Buicks and then Jeeps from the early to mid-60s to the early 70s. We have one in our CJ-3A and with the overdrive the thing will hit 80 if I really want it too... though with the loose steering and tiny brakes that doesn't really happen. I've done 65 on the interstate relatively comfortably though. Amazing power and low-end torque, especially in such a light vehicle

The 231 came out after the 225... very similar engine... slightly larger bore I think but not sure. It's actually still being used today in a few front wheel drive GM cars, though now it's called the 3800 (3.8L) and has modern fuel and ingnition systems.

If you aren't afraid of fuel injection a cool swap might be a 3.8L out of a late model camaro. I think those were the last rear-wheel drive ones. Might be overkill for an otherwise stock flatfender though.

A modern 4-cyl would also be a good idea. The iron duke is a great engine if you could find one setup for RWD.
