BB Auto Tranny Question

I took a closer look at the engine today, It does not have the flat area where you would see 440 stamped on it. I was wondering if anyone know how I can tell what the engine is? I know that it will say on the left side of the block, but I can't get under the motorhome right now.

here is the Vin if it will help...

I have done a couple vin decoders, and it comes back as a hemi! I wish.
