Thanks guys..
From what I've read they are 3 car 360 oil pans, 392 is suppose to be the correct for the F-body I'm working on. Their is also a 876 pan not sure what it fits. And this 438 pan from the 71-73 C-body. I went ahead and bolted to to a bare block and set it down in there to make sure it'll fits and clears everything before I bolt it up to the rebuilt 360. It fits fine! 👍👍
