Re: Which motor mount frame pads
1964-67 small block and 1965-67 big block frame brackets are dimensionally the same, the difference being a notch/relief in the BBC brackets to clear the original BBC motor mount interlocking tabs. Either bracket will work if you use something like Energy Suspension 3-1114G polyurethane mounts.
