That data sticker you showed is something they put on every engine showing year it was produced and engine serial number. It could of been uprated by now, I think the only way to find out what it is currently set at is to hook up to a computer. The hp rating on your engine when shipped from factory was 355. The serial number plate is typically found on the back of the engine block. Please enter a valid serial number beginning with three alphanumeric characters followed by numeric characters (e.g.: XYZ01234).
