No. The bore and stroke are different for one.
Actually, from an older thread "318 and 360 block are not the same
3.31x3.91 stroke/bore vs 3.58x4.00 stroke/bore.
318 internally balanced, 360 externally balanced.
Max stroke for a 318 is 390ci vs 360 with 426ci. (wont recommend it/408 better choice)
Both motors do share the same tb, intake manifold and heads. " Excerpt from RM_INDY's post.
