External dimensions of 454 and 396 engine blocks are the same. Your 396 should be a short water pump. You will want to remove all the brackets from the 396 and transfer them to the 454. The 454 should drop right onto the engine mounts in your 67 truck. You will have to use the old style mounts on the engine side. This is assuming that your truck has the 68-72 style mounts on the frame.
