Is there a way of knowing if the engine has been swapped. It may show up on the CARFAX, but if nothing shows up is there any way of checking?

Compare the engine block number with the VIN or chassis number. It's usually found on the right hand side of the block facing forward.

Yes, match vin to the vin on the block. The chilton repair manual will tell you where to look
