Engine mount 1968 340 barracuda

yes, AFAIK, and I could be wrong, but all A-body biscuits from at least 67 to 72 are the same. and they fit all small block brackets. Biscuits are often listed as engine mounts.

But, as @4spdragtop said,
as for the metal brackets, the 340/360 engines have only 3 bolts on the one side versus 4 on the other, and the lug spacing is different on those. I forget which side is different.
In a pinch, the 318 brackets can be adapted to the 340 lugs.

These are the right biscuits
