swap 1996 318 EFI onto 1967 273?

If Magnum heads would bolt on, and it was an auto, it would probably be easy to do. Not sure the 273 bore is big enough for the 1.92/1.625 valves.

If the bore is big enough, bolting the heads on would allow you to bolt the intake on. After that, the last hurdle would be swapping the flex plate so the CPS would have notches to read, and then building a mount for the CPS.

There is a place that sold a mount the used the trans bolts, for like $75 or something. I’ve also seen some one use a piece of angle bolt to the back of the head to create the flat plane needed to bolt the CPS to.

Could all be done, provided the heads bolt on without conflicts with the valves.
