360 HP Confusion. History of this motor?

Hp 360 engines had premium cranks (CFD), shot peend if I remember correctly and a factory windage tray that fit a 360 only, I only had one out of a 76 cop car. They had the updated 340 cam, and the exhaust valves were .0005 undersized as well as chrome plated stems. I have some NOS 1.88 intakes for the cop motors, I think they were also different also but would have to check. Double roller timing set and the thrust plate with the hollow bolt. TQ intake and carb. 727 Auto trans.
