Upgraded 360 Cam?

Once again… What year of 360 and what did it originally come out of? And how many miles? Unless this is a fairly fresh engine, I would save the Eddy heads for a fresh build and a whole next level of planning.

It's a 76 that came out of a motor home with 727. I think the engine had about 80k miles on it when pulled
