Reverse Rotation Crankshaft Question

i think op was asking about crank differences only......

cams are different, yes, i have a scott brown custom for my reverse rotation 318.....but the question that nobody could ever answer me when i rebuilt mine, was if the pistons go in backwards since the major and minor thrust surfaces are opposite of conventional rotation engines.
in my case, my aftermarket pistons have zero wristpin offset, it didn't matter, but it was/still is a question i always ask the marine guys and they can't give me a straight answer (i think i know the answer though).....
