How big is a early a body trunk?

You can put a 340 in there, piece by piece, but if the tubs come down on the tires you can't drive it anywhere, so I guess that would be at least 340 cubic inches, or 340 pounds which ever comes first.

Not an A but how about a 451? Trunk even shut.

picked up a complete 318 in my Breeze and even packed up a breakdown cherry picker in the back seat. Had to remove the heads to make it fit.
