Not sure on 91 but on Magnum engines the cam snout is to short. Put a 96 360 Magnum in my truck and wanted to keep mechanical fuel pump. Got adapter from Hughes Engines. Here is link:

Take the cover plater off and look/feel for the eccentric.
I built my 360 from a TBI B250 van and the front cover has a plate on the fuel pump mount. (It had no pump eccentric on it as I recall.)

Yes you could add one. (The roller cam is shorter than the cam gear and uses a thick washer to hold it down.) You will need the remove the timing cover and install the extender listed above (post #2) if you use the roller a cam, the engine will have. (With an eccentric)
The alternative is to use a flat lifter cam and find the special washer that goes over a longer cam snout and holds the eccentric against the cam gear.
