5.9 Magnum FI cam upgrade

Hi, I'm new to the forum. I dont have an A body as I've been into the 46-52 Plymouths for a long time but you guys have the best small block Mopar tech I've seen on just about any of the Mopar sites so I signed up. Lots of great rides and mechanics on here!

Im planning on doing a 5.9 magnum swap and utilizing the factory fuel injection along with an AX-15 5 speed and a 3:73 geared 8.8 in a 49 Plymouth coupe. Can anyone recommend a cam upgrade that will work with the factory fuel injection? I'm assuming I'll have to have the computer reflashed but would like to stick with the factory FI main componants. I dont have an engine yet but plan on using an OBD II setup.
