Shouldn't be one in a beaumont, since there were no L78's. If you did come across one, you might want to snap it up since it has some value to anyone building a L78. Are you planning on building a 396? If you don't have the orginal engine i'd say build a 454, you can tell everyone it's a 396 and make more horsepower...you can build a 496 for the same price as a 396! I wanted to say I had a 396 in my car, and found one (although my car is not originally a 396)...in hindsight I should have went bigger for the cubic inches and easier HP.
I would think anything is possible, depending what may have been available or in short supply at the time in the factory... I typically do my research on the Team Chevelle website, what i've seen is a bit inconclusive, the engine codes are the same for many 2 or 4 bolt 396's and 402's...
I had an L34 66 Chevelle that had the original 4 bolt block. I was told that those were leftovers of the 65 Z16 blocks but who knows ?? It was a Nov 65 dated block if I remember right.

That is what I have always held, that early production 1966 L34s had early 4-bolt mains in their 396 blocks (not necessarily Z-16 engine blocks per se), but during production switched to 2-bolt mains. All subsequent 396 blocks except for L78s were 2-bolt. I don't know about the pickup 396/400/402 blocks, but the 1973+ 454 pickup blocks were 2-bolt mains. A 2-bolt big block has a lot stronger block than a 2-bolt small block. The main webs & bearings are so much beefier on a big block.
