383 vs 360 in an A 68 Cuda

not a shoehorn....all kinds of room on a low-deck big block. This one has OEM K and manual steering, Schumacher conversion mounts, 833 / 4-speed, TTi exhaust.
the only mod was the #7 primary header tube need modified (cut and slightly moved) for clutch shaft clearance. Since this build about 10 years ago, maybe TTi changed that pipe because the mod would work with auto also.

Might be a little tight with power steering.
