What engine in a flat fender?

To be more specific.
What engine can I get into a low hood flat fender like a CJ2A?

Please note that I'm on the wrong side of the pond over here in England.
Our wrecking yards contain very few American built vehicles, they tend to exist only in the hands of "specialists", (read top$$$$)

Logic tells me a small V6 or V8 is probably going to fit when an OHV inline will be too tall.

So what can I go for?
GM V6? 3.8, 4.3?

I'd expect a carburettor engine to be lower than injected but I'll consider anything.

 

Have you considered the 2000/2300/2500cc Ford? Those might be widely available there. http://www.novak-adapt.com/knowledge/pinto.htm

Other popular 4-cylinders include the GM/Mercruiser 3.0L, the Chevrolet 153, and the GM/Pontiac 151 (aka Iron Duke, GM cars, Jeeps). A Jeep 150 is also a good choice.

Avoid inline 6-cylinders (too long), but the inline 4's work fine.

The Chevrolet 4.3L V6 is popular here, as are the Buick V6s. Chevrolet V8s used to be popular, but have mostly been displaced by the V6s because the fitment of the V6 is much easier, and the V6s are widely and cheaply available.

 

Cheers!
I didn't realise the Iron Duke was popular for flatfenders.
I might just find a 1980 CJ7 with one in if I hunt about for a while.
Otherwise GMs V6s do keep coming up over here, usually in Chevy vans, S10 Blazers and late Firebird/Camaros.
Non of the above fetches big$$$ over here especially if there's work to be done.
I've got to admit to knowing next to nothing about GM V6s but I learn fast!

 

There's a 60 degree V6 and a 90 degree V6. Not an expert on this, but I think you want to avoid the 60 degree engine and pick the 90 degree engine. The 60 degree engine (2.8L) was used in the early XJs, came in both longitudinal and transverse versions, and is troublesome. The 90 degree engines are all longitudinal mount, which is what you want for a Jeep. Novak has a page about the 90 degree engine (4.3L). The Gen II and Gen III 2.8L may be ok - ask for more specifics in the early CJ-5 forum if you don't get some good replies here.

Cheers Tim.

The 90 degree V6 seems to be the one to go for.

Enough cubes for some real grunt, but about the right age to be in a hole on prices.

Not old enough to be sought after, not new enough to interest anyone.

 

I've got a 2000cc Pinto engine in my 2A. It was a relatively simple transplant. We did move everything forward 2" so the engine would clear the firewall. It runs, it works fine, and for the most part I've been happy with it. Now my Jeep has 5.38 gears and only 31" tires. It's great off road (I've never had a problem with not having enough power), but is a bit of a slug on the highway. I've driven it on the highway, and I'm usually in the far right hand lane, shifting in-and-out of overdrive (Warn OD with T-90 tranny). Around town it's fine. If the Pinto engine ever blows up, I'll probably go with a small V6 the next time.

 

The 1.6 and 2.0 pinto engines were fords bread and butter engines over here.
The Cortina 2000E I had would wind up to 110mph on a good day.
But that is a car, a jeep has the aerodynamics of a brick!

But if I'm going to the trouble of a conversion job I think I'd rather get something with more capacity and torque.
