Block heater is 1000 watt, if I recall correctly. Yes, you can just replace the cord end with any standard 115 volt 15 amp 3 wire (grounding) cord end. The factory cord is flat, the center wire is the ground (green wire, or green screw), the side with the ribs is the neutral (white wire, or silver screw), and the smooth side is the hot (black wire, or brass screw)
Another popular option is to get a fixed mount male plug, drill a hole in the bumper to mount it, and then no more dangling cord end... check out the general 7.3 page and do a search for block heater cords, something should come up... "merinco mod" maybe?
