Looking for some advice on a 360 magnum swap

Some of the magnums come without AC and use a shorter belt. My Dad's '94 Dakota was this way.
I personally like the LA front on the magnum.
If you want to run a fuel pump on the stock magnum cam, hughes makes a kit for the eccentric and it is not expensive at all.
Another option is a LA roller cam ('85-91). Many of them have the long nose for the fuel pump eccentric. This is what I did on one of our vans.
