really the 3 biggest things are new bellhousing (4wd Hardware), engine mounts (4wd Hardware or fabricate your own) and custom exaust. i used hooker headers (Performance Automotive Warehouse) and cherry bombs, or just wide open headers

CJ Lover What tranny are you running and what axles do you have? I am putting a 350 in my 76' CJ-5 and haven't decided on a tranny yet. How are your axles holding up.

The gearing in my opinion is most related to what size tires you are going to run. I put a Vortec 5.3 in mine with a 4L60e auto tranny. I used 4.56 gears to match my 35s. Don't have it moving under its own power yet, but it sure looks good on paper anyway!

JP7,
I pulled my 304/T-15 a few years ago. Pretty easy swap, call Advanced Adapters and get the scoop and parts directly from them. They've got it all and are the supplier for most of the parts houses. You'll need motor mounts (AA has bolt in or weld in), bellhousing (depending on trans/engine combo), and trans/transfer case adapter at the least. More depending on parts selection. I'm running a warmed over 350 with a NP 435 4-speed and a Dana 20 transfer case. I mated the trans to the 350 using a stock chevy mid 80's hydraulic clutch bellhousing and aftermarket clutch assembly. Used the stock Jeep (4 cly Iron Duke engine) clutch master cylinder and chevy pickup slave cylinder. NP 435 to Dana 20 'case was AA and dropped in 3.15 low gears while it was apart. My axles are Dana 44/Dana 30 with Detroit Locker and 4.27s. Gear carrier and gears will work in either axle housing. I like the gears, a good compromise between crawling and the occasional highway ride.
