1965-66 396 engine identification help!!!

I recenlty aquired a 396 casting code 3855961 which tells me it is a 65-66. The problem I am having is the stamp pad numbers, specifically the suffix code. The numbers read as follows T122IIVR I could be mistaking an I for a 1 but I can't find any VR suffix codes. I do find IV which would be correct for the 1965 but where is this R coming from??? I have researched the web for days and have the chevrolet book of numbers with no success! Save me from my misery!!!!
Thanks for any help!
Randy

hello saw your inquiry and i did a little research and found some info for you on the 3855961 number, it could be 1965-1966 2or 4 bolt block 396 or it could be a 427 1966 2bolt block hopefully that might help a little bit more thnx

Thanks for all the input guys! I was hoping it to be date correct for my 1965 Impala SS, maybe should find a 66?
Thanks,
Randy

I think I still have a 396, IVR code, I'll look at the casting date and see if its a 65 block.
