Dumb qustion about jeeps

Short answer is no - the valiant engine was all Australian and I don't believe Jeep had anything to do with Chrysler until much later.

Gazzz

Jeeps six , is the same engine since the 70's with changes like injection and further refinements

Have to agree with above, yes they are an older technology motor, that's not a bad thing in comparison to todays electronic management, had a couple of them very very reliable They continued to tinker with them right up till the straight 6 just departing. To the best of my knowledge the comparison with Valiant is the word "HEMI", they are still using that on the just released new model V8's and refers to the Hemi configuraion in the cylinder head, a design feature of the combustion chamber.

My understanding is that the Valiant motor will bolt up to the 4Ltr bell housing..Any takers?..RockyOne!MPG:7!

Over the years JEEP have used a number of engines from various manufactures – Ford, GM, Chrysler, AMC and now Mercedes.

The 4.0L (258ci) straight six was the last engines that were used in the AMC cars before JEEP bought them out in the late ‘80s – e.g. – Rambler.

They are a good strong engine but were difficult to adapt the emission control components to in the early days.

Cheaper to use a known engine rather than redesign a new one for the Cherokee / Wrangler plus it suited the American market. It was the “don’t fix it if it ain’t broke” philosophy for the engine usage.

But I'm sure there are some hardened JEEP followers that will have a say.
