Post those numbers in the Engine Forum and someone will tell you for sure exactly what you have. There is also a Vin Buster in the tech tips. Gosh, just so much info here it takes a little time to get acquainted with all of it..... and you might want to introduce yourself, and show pictures in the Big Bolt Forum. Guys there know a lot about big trucks.
Not everyone that signs in comes through the welcome center everytime and may not see the info you posted.

Trucks will pay their way, where a car is an absess on a mans pocketbook!

I'd rather walk and carry a Chevy hub cap than ride in a Ferd.
I can explain it to you, but I can't understand it for you smile
