Engine/Trans bolt patterns

[Lakota]

Can anyone tell me if a 70's Olds 350 and a 70's Chevy 350 have the same transmission bolt pattern?
If not, can anyone tell me where I can get an adapter plate?

Speedway has an adapter plate...is this what you're looking for? You may need to call for better details. Depends on what they mean by "vice-versa".

Thanks,
That's what I was looking for. Speedway didn't have it listed in the catalogs I have. I guess they missed it. Yup, it can be used either way. It's listed as an adapter to mount any BPOC to a Chevy TH350 trans, but by reversing it, you can mount a Chevy 350 to a BPOC trans, and that's what I'm looking for.
