I have a 1975 grand lemans. Just did an engine swap from a 4.1 250 to a 1974 6.6l 400 bb. Question: the 400 ran before we put it in. Now it won't even turnover. Power to everything, won't crank.

Yes. We can turn the engine as much as we want. And the transmission is the mated TH400 from the donor car.
