Several differances between small and big cam. If you mean how can the uninitiated tell which is which, look at the left side of the block, below the pump. A big cam will say just that, BIG CAM cast into the block just under the lifter blocks. also the data plate on the left side of the accessory drive will say what it is. The 855 means 855 cubic inches. both big and small cam were 855 cubic inches, and NTC can be found in both small and big cam. in other words, you will find both 855 cubic inch Small Cam (which will NOT say small cam on it) NTC 300, NTC350 etc.... and 855 cubic inch Big Cam, Big Cam II, Big Cam III and Big Cam VI. There are several differances in parts mounted to both blocks, and most are interchangable. BUT! the blocks are differant, in that one has a cam size used by Cummins for years, and one has a much larger cam bearing diameter. One will not fit the other. The cam follower boxes are differant sizes also.
