LSA Crate engine Ship with oil?

[AEH]

I bought a new crate engine last fall from a Chevrolet dealership in Colorado. There original ship date to them was 2018 so they had it in their inventory a while. Still in the crate, plastic and paper intact. I read the GM paperwork and they say to prime the engine with oil so I assumed it was shipped with no oil. I’m swapping to a LS1 oil pan for clearance so I just rolled it over on the stand to remove the pan. Wasn’t long till I felt my leg and looked down to see oil pouring out in my shoe and all over the floor.



I never even pulled the dipstick but it had a full 8 quarts in it if I added in what was in the floor and my shoe. So do they ship them full of oil, or did the dealer add the oil possibly to prevent corrosion, etc. I pulled the filter and it was full, but it had been upside down. Just wondering if I still need to prime it or has it already been done?
