If you mean the crank they are the same. The 2T was used in both 360 and 330 applications. The heads might tell you more if your talking about the engine. 330's were FT engines and had the heat crossover in the center vs offset like the FE's. The bore size of the 360 is 4.05 stock like the 390. The 330's have a smaller 3.975 cyl bore. If you know the head casting numbers post them and we can tell what they are. Glad to help.
