There are a few main things to look at; one, like fmthefixer posted, is the motor mounts. Get under the Jeep and look at the mounts, make sure they have rubber and that the rubber isnâ€™t cracking and deteriorating away. Next make sure that the welds from the motor mount to the frame are good strong welds with no signs of cracking. The frame should also be boxed in around the motor and the steering gear box. Also check around the steering gear box to ensure that the bolts arenâ€™t trying to pull through the frame.
Next problem with a V-8 swap is heat. The stock radiator for a four cylinder Jeep engine wonâ€™t disperse enough heat for a V-8 so look for a quality radiator, mine uses a triple row aluminum radiator out of the Corvette the engine came out of.
Stock Jeep axles and transfer case will handle the motor, for the most part unless you get crazy with the wheel size, but if you just want to identify them, your rear will be either a Dana 44 or AMC 20. The Dana 44 Differential Cover will look like a diamond lying on its side with ten bolts holding the cover on. And AMC 20 is perfectly round and dished out, looks almost like an old hubcap. The front will probably be a Dana 30, since you said itâ€™s got a Dana 20 transfer case Iâ€™ll assume the Jeep is at least a â€™73 model or newer and it that case wouldnâ€™t use the older Dana 27 like my â€™60 does. Easiest way to tell is to look at the knuckle, if itâ€™s open and you can see the u-joint; itâ€™s a Dana 30. If itâ€™s closed with washers around it that are probably leaking grease, itâ€™s a Dana 27.
Sorry I donâ€™t have any help on the disk brake conversion, no experience with those, yet.
Be sure to let us know how it goes.
Edit: I almost forgot drive shafts. With a V-8 swap youâ€™ll probably have custom drive shafts front and rear, all I can suggest there is look for quality welds. [ 01-26-2004, 04:06 PM: Message edited by: Frank-N-Jeeper ]
