The 514 would be hard to determine externally...but they are based on the 429/460 engine. That has a thermostat housing that is parallel to the top of the intake that it attaches to. The Cleveland based engines( 351C,400&351M) are the only Ford engines that use a fuel pump pattern that is vertical, all others are horizontal. The FE engines have the unique feature, among the V8s, of having part of the intake make up the inner portion of the head, so it is partially covered by the inside of the valve covers. Most any of the others will Windsors. The easiest way to distinguish between the 351 and the smaller variants is at the dist hole. The 351W has about an inch rise between it and the front of the intake ledge. The smaller engines have it about even with it.
Now internal dimesions are pretty hard to determine without a cylinder test, like use at some race tracks or a partial disassembly. There are common sizes within the engine ranges, a 514 as you mentioned is based on the 385 series block( 429/460), 408s are common in the 351W block ans 342s are usually the 302 based engine. These are some of the common sizes and there are a veritable range that they can be. But again, externally, it is hard to distinguish sizes.
If they are built by a regular engine supplier they most likely will have some #s that were stamped and can be traced by that. Good luck.
