Do you mean BBC frame monuts, or motor mounts? The motor mounts on a SBC and BBC siit in the same position, but BBC motor mounts are taller than SBC motor mounts. The frame mounts are different, but not sure in what way.
I could never run tall valve covers on the 427 in my Camaro, as they just wouldn't clear the heater outlets, and the brake booster. I even ran SBC motor mounts to drop it down, and still not enough clearance.
