So I'm looking into purchasing this block for a build and want to see if I can get some help identifying the engine. Other numbers I have are 18N346181 and VII13MA. Any help would be appreciated ty

It is a 1968 only block. This particular one is from a 1968 Camaro. The MA code identifies it as a 210hp 327 built at Norwood. 1968 blocks were the first year of medium journal blocks like all the 350 and 327 blocks produced after that. With the proper rotating parts, you can build anything from a 302 to a big inch stroker with the block.
If it still has the original heads, they will be small valve heads for this low HP engine with 1.72" valves. These heads are not a good choice for performance.
