How does this 360 Magnum combo sound?

I would try a cam more like http://www.hughesengines.com/partDetail.asp?partID=10057&eTypeID=10
For the head I would go with the EDDY magnum with the magnum manifold. I like the vertical manifold bolts. Lastly the Magnum serpentine belt is WAY better then any v-belt. Less drag, less headaches. V-belt conversion on a magnum is a pain. IMHO.

I don't know if you realize that the 98 Jeep block was MPI and reverse rotation accessories? Because of this, I am definitely not going to be able to keep the magnum manifold (though the motor came without a manifold anyway).
