If it's the f-head engine (stock) it is 150 cu. inches. Nothing is a bolt in without some sort of adapters or different bellhousing. Cooling anything bigger would be an issue as would motor mounts.

How can I tell if its an F-Head?
Is the 4cyl. strong enough for the Jeep?

Being somewhat "familiar" with the older CJ's, I am going to "throw out" that the Buick V6 used in those years would be an awesome transplant. It's a 226ci, and has GREAT HP and Torque ratings! It's a powerhouse, and I will hopefully own one some day!

Everyone feel free to add to this, that is familiar with them.

Gotta agree with 4x4CJ on that one, however the displacement is 225 cid. The 226 was a straight 6 put in wagons and p'ups. I've owned two of these(still have one) and the motor is awsome! Small, lite(compaired to a V8) good gas milage, and incredable torque due to the heaviest flywheel you ever saw. The nicest thing is they came stock which means that they FIT with a minimum of effort. As for your F head, they provide enough power for putting such as fireroading and mild rockcrawling but will be lacking for the more demanding wheeling, such as mudding or the more extreme climbing. If your happy with the preformance of the 4, then rebuilding it will be cheaper and your Jeep will remain stock(sometimes a big plus when going to sell it on down the road).

Yeh, sorry for that one...I knew what the 226 was, but had it in mind when I was thinking of the Buick displacement, LOL.

As the electricians say, "220, 221, whatever it takes!"

OK If I wanted to replace the factory setup with the Buick, and I wanted to get the parts at a Junk Yard, What would I ask for?
Is there a car or truck that had all the right parts for the conversion to V-6? If not what kind of torque does the 4cyl. f-head put out? I just want the best thing for the 69' CJ5.
Also is there a fuel injection system that can be retrofitted to the Buicl V-6?
