Any reason you didn't just bolt the BBC into your car with the SBC mounts? They would have bolted right up with no issue if you used the SBC motor mounts also.
I don't know of a template. I'd drop the engine in place and either tack weld the mounts so I could rill them with the engine out, or if possible mark the holes to drill with the engine out. PITA, but not much else to do.
