Actually, I have stated before...the LZ9 3.9L sounds very much like a BMW I-6.

It's not purely an OHV vs OHC issue. How much power does the 3.9L produce? 240hp or so? Not going to cut it.
Second issue... Cadillac needs the 3.6L no matter what. I would bet, dollars to donuts, that it's cheaper for GM to take the variable cost hit per engine by offering only the 3.6L across the board, than it would be to offer TWO families of V6 engines (THREE, counting the 3.8L Buick engine), while benefiting from a small cost savings per engine on a variable basis.
