98 Jeep magnum

Hey Guys - I just bought a 98 Jeep Grand Cherokee Limited Special Edition! Wow, that's a mouthful!
So far I have $125 in a 5.9 Magnum and Dana 44A limited slip rear with disc brakes. Not Bad.
I also have a camshaft from a 92 Dakota 5.2 from a previous purchase. Of course, the 5.9 has the cast iron manifolds that fit really well in an a-body.
Next winter I'm going to put the 5.2 cam into the 5.9 and do the modifications to the kegger.
I think I'll be looking for a a suitable D100 or a 71-72 Roadrunner to drop the 5.9 into. Of course, I'll go with the factory PCM.

The trans had already been removed from the Jeep before I bought it. So - I'm guessing I will have to find a TC from a 360 engine? The external balancing is done with the damper and TC?

I read somewhere the reasoning behind the external balancing for the 360 engine. But I forgot - I've slept since then! Can somebody refresh my memory on the subject? Thanks
