I'm stuck in the same situation, D30 / D35 ...
So I'm just gonna run them until they break and then buy a D44 ...
Problem is I also have the damn 3.07 gears :(
Here is a complete bolt in D44:

I have had GREAT luck with my AVON viper SPORTS :) ...
So I would think you will get some good mileage out of those COBRA's
I recommend AVON's to EVERYONE !!!

I agree with the above my Vortec 388 (4.060 bore x 3.75 stroke) runs at 165 ... mid August at an idle, in deadlock traffic .... no heat issues AT ALL :)

When I read the thread title "buggy" to me said:
4.3L or even S/C 3.8L
But the RAMJET does seem like a GREAT option !!!

GREAT question, I'd like to wheel without the top and doors but don't want to drive / tow the Jeep down to Moab without them ....

P.S. The hotel is a great idea for the doors !!! :)
