What motor to go with?
NO 360s have forged cranks unless its an aftermarket forged one. All 360s have the heavy rods. Never seen any 360 heads stamped hi po or have big valves from the factory. What are the head casting #s? Most likely normal 1.88 360 heads. How well does the seller know his mopars? Every "stock" 360 ive tried and owned are dogy. Good cruiser motor if that what your looking for. I think this hi po stuff is going to sellers head. A good going early 318 would probably beat it. I personaly like 400+ HP
