Wow, I have been posting a lot recently.

I just received a free 1970 Scout 800a. I was told the motor is a 345. It has an automatic transmission. I need to identify what the motor actually is. Where do I look for engine and transmission ID numbers and where do I find out what they related to? Also, the part of the VIN is missing from the sticker around the door and I cannot seem to find another location for the VIN, where else would it be?

The engine appears to have brass valve covers. Would this be the case?

Thanks so much.
