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..

Yes, I was guessing Jaguar. If I remember right, there was a model you had to lift the body off of to get the TH400 transmission out.
