    Hello, I have an 85 210 cuddy and the first owner replaced the engine but Im not sure if he upgraded from a 5.0 to a 5.7. the air cleaner says 5.0 and the new engine has a serpentine belt. It has a Mercury tag on the block with a serial number L052291. Any help on how to Id engine would be great.
