Magnum 318 info

Got a chance to buy a stock 318 and trans out of a 96 Dakota truck. No clue on ether. Assume it is a magnum motor with a roller cam and an electronic 4 spd O.D. trans? Is this a good block to build from? Looking to make a very mild street set for my 74 Duster to replace the existing / 6. Can get the engine and trans for $500. Was running when it was pulled a short while ago from the Dakota. Any info would be appreciated. Thanks, John
For that price it should be a 360. I’d wait for one to show up, unless you’re in a hurry to spend money or help a friend out.
