D you happen to know if the Cadillac 390 shares a bellhousing bolt pattern with any of the other GM engines- - - - -possibly Buick/Olds/Pontiac? I'm thinking about trying to mate up a 390 with some variation of a turbo 350 or 400, possibly. Currently, it's got a Controlled Coupling Hydramatic on it.
