Stacey, the frame to engine mount brackets are different from small block
to big block, however all of the hole locations are the same. The difference is
that the big block brackets have a strengthening rib that runs around the bottom
toward the front, also it has a notch to clear the interlocking tab in the big
block engine mount.Phil is correct in stating that you must use small block
engine mounts with small block frame to engine mount brackets, but you can use
small block or big block engine mounts with big block frame to engine mount
brackets. If you try to use the big block engine mounts on the small block frame
to engine mount brackets, the interlocking tab will hit the bracket before the
engine mount gets in the correct possition, you wont be able to get it to line
up. I found this out the hard way. I had to cut the tab off before I could get
everything to line up. Here are some pictures that might help, the big block
mounts are in the middle. Frame brackets
