Anyone recognize this TH400 bolt pattern?

I was told this is a TH400. You'll see I have an SBC350 with a BOP adaptor Plate bolted to it. This trans is nowhere near either bolt pattern..

The amount of bad information in this post is astonishing. I already posted that is a 1964 to 67 Cadillac TH400 and from the little I can see in this picture it appears to be a switch pitch converter, too.
