There are anomalies in those numbers, Alton. The first two digits of the Model number are normally the engine's displacement in cubic inches, which I think is 31 for yours, not E1. More importantly, the Type needs an extra digit. There are four numbers for the type, then usually a hyphen, and two numbers or letters for the trim. The hyphen may be omitted, but there should be six numbers or letters altogether for the Type/Trim, so there is one missing in what you posted.
Incidentally the Code tells us your engine was made on 10 February 2010, so as you said, it isn't all that old.
