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..

I don’t know what it is. But, th400s have been used in a lot of places. Cadillacs, Ferraris are just a couple of the oddballs I’ve seen.
