Hello! I have a 1980 ramcharger 4x4 w/318 AT. Can anybody tell me what tranny came with these and what years the engines are compatible?

 

727 torqflight (torqflyte ?) transmission, you can use any 70's or early 80's ( carburated)318's but better yet 360's as long as you also get the torque convertor and vibration damper for the 360....the 360 has the same waterpump and thermostat location so your rad hoses will be in the exact same location
