Help 360 Magnum dumped all its oil when started

View attachment 1715350186 Hi guys, I have a 74 barracuda with a newer 360 Magnum crate engine, with about a 1000 miles on it and a year old, I changed the oil since its been about a year since the engine was installed. I went to start it up and it dumped all its oil on the ground. Looks to be coming from the bell housing I'm not 100%, not a trace of oil on the oil pan near the drain plug and the oil filter is really clean other than where it faces the bell housing which has a small amount of oil on it. Headers are clean directly below the oil filter. I started the car up, let it run for about 45-60 seconds, then pull out of the garage. Sounded like a rougher start then normal, then I heard the valves tapping and some smoke so I shut it off. Ran for maybe a minute. Any ideas? I thought maybe the oil pump or rear main seal blew, but it looks like all 5 quarts ended up on the ground in less than a minute! I have no idea why. See Pic for the oil "spot"
