*IF*...
(And that's a BIG *IF* with Jeeps and their PO's!)

'79 CJ-5 with V-8,
Should have a 304 CID V-8 Engine,
Displacement on AMC V-8 Blocks is embossed right in the side of the block next to the engine mount, so you should be able to EASILY identify it...

On top, you will have a Motorcraft 2100 Carburetor.
Not a bad off road carb, and still used by a BUNCH of us today since it works.
The 2100 is a Holley design, and may of them were built by Holley, so if you can tune a Holley, you will find the MC 2100 VERY EASY...

'79 Will also have a Jeep/Motorcraft ignition with 'DuraSpark' module.
Distributor Good, Coil Fair, Module leaves something to be desired.
Easily upgradeable, even in 'Emissions' states.

Alternator will be a Delco Remy SI
series alternator, a 10 SI to be exact.
VERY reliable and easily upgradeable that is a direct bolt in.

Steering box is probably a Saginaw... and is upgradeable to a Variable Rate box by getting one from a little newer version of FSJ (Full Size Jeep).
The variable box is a bolt in upgrade.

The Front Axle will be a DANA 30.
All CJ's from '72 to end of production in '86 used Dana 30 Front Differentials.
Weak, and 'Upgrading' them is like putting pearls on a pig...
No matter what you do, it's still a small, weak Dana 30.

The Transmission is a good question, and the best source of information on that subject is here,
http://www.novak-adapt.com/knowledge...on_gateway.htm

The TRANSFER CASE will be a Dana 20, strong, but not the best version to 'Twin Stick' and it's not adaptable to 'Low Crawl' ratios like a Dana 300 is.
Personally, I've NEVER had a Dana 20 leave me walking, and I beat the CRAP out of them!
But I TRAIL RIDE with MUD obstacles, and not 'Rock Crawl'...

The Rear Axle Will Be An AMC (Spicer built) Model 20 with the differential centered.
Easy to spot by it's perfectly round rear cover with 12 (Torx head) bolts ...
The center housing, pinion, ring gear, and differential carrier are all fairly strong,
BUT,
The CJ version has weak, thin tube material, small, failure prone wheel bearings, Two piece Axle shafts, and small brakes.

All CJ-5's were 'Narrow Track', where later CJ-7-8 vehicles went to a wider axle...

The only CJ past '74 with a Dana 44 in the rear was the '86 CJ-7, and that axle will be wider than your current axle.

Springs went from 2" to 2.5" in '75, so you have the 'Wider' springs, and that will make things easier when you decide to change springs or axles.

If you DON'T have a Tilt column already (Fairly rare in a CJ-5) the Tilt wheel from any FULL SIZE Jeep Wagoneer from '86 back will drop right into your CJ.
I've used several of them, and it's MUCH easier than trying to use the 'Chrysler' version of steering column, or rob one from a GM vehicle and adapt it...
(Jeep used GM steering Columns, But the FSJ column works best if you can find one)

Wiring on the '79 is minimal, but confusing, and it's the first year of the 'standardized' fuse block.

That's all that comes to mind right now, but if you have specific questions, feel free to ask...
