70 Camaro big block/small block motor mount question

We just bought a tubbed/caged 70 Camaro less motor and trans. It had a 454 big block in it, and we're putting a 386 (4.155" bore/3.56" stroke) small block in it.
Will the frame part of the big block motor mounts work with Moroso Solid block mounts?

Thanks,
Frank

Yes.
