I've owned several cjs 4, 6, and 8 cylinders all have been daily drivers and this is what i can tell you from experience.

my first jeep cj7 4cyl with 33s = no power, slow on incline on highways.

second jeep cj7 8 cyl 360 with 33s= lots of power and nice sound but 15 gallon tank will be empty at about 100 miles or so. It was bad on the wallet, someone here said get a 20 gallond tank i will agree.

third jeep cj7 6cyl 258 with 33s= best of both worlds good in gas and plenty of power for what i need as daily driver and occasional trail riding. But i do
miss the sound of that 360, and i've been thinking in installing a 40 series flowmaster which it will make my 258 sound alittle better but never quite like the 360. good luck.

What is the weight difference between the 4.2 and the 360?

"Clevor" is the nickname for Cleveland heads on a Windsor block...I believe.

Go for it! You will not be disappointed.
All that about 6's is great until you drive it with an 8 in it!
You may pay a little more in gas or you may not.
I'm getting 16+MPG. That's with a correctly programmed speedo.
I'm running 32's and 4.10 gears with a TBI 350.

Swap in an OBDI 4.0l HO from an XJ. It will give you 6 cylinder longevity and "economy" and be an easier swap. It will have more power than you need to run on the highway and it is only really an upgrade, not a swap.

V8s are great but as a DD do you really want that level of cost?

My 258 is a daily driver and is surprisingly reliable for a 30 year old vehicle. The economy is probably not great but at 40c a litre I do not mind.

The guy I gave my 258 to was pulling a very stout AMC360 from his 5.
He was an older guy that said the 360 shook too much!
