I ran across a cheap 1970 440 that came from a motorhome, it runs like a top but the waterpump setup is different than the normal 440. It has water jackets in the front of the heads and thats where the waterpump circulates from. Is this motor worth having, can I put a regular waterpump on it and block off the ones on the heads? The heads have the water jackets at the rear of the head also but have block off plates over them. The exhaust manifold bolts are located differently than normal also, the center has three bolts and they are staggered (one bolt high and one low) instead of side by side. Is this an industrial motor?
