360 LA Block Questions

The casting of the block is the same between truck and car engines. I am not sure if your 318 mounts will work on the 360 but I believe they will. I do know 340s are different but I have modified 318 mounts for my 340. Standard bore size on the block is 4.00” and .030 over shouldn’t be a problem at all. What year casting date is the block?
