V10 Magnum swap?

Guys, stop me from making a poor choice, tell me a 2002 V10 Magnum out of a truck won't fit, because I just got a lead on an engine, transmission, ecu, harness, etc., soup to nuts, for $650 obo wants it gone.... which means i can pay less.

Tell me it won't fit. Otherwise my wallet will be lighter.
