The 4 inboard head bolt / head stud positions, can you make a wedge block accept Hemi heads ? No tsk You need the cast in holes for the inner head studs to seat against also scope

I know the main caps won't be the same.

Isn't the only really tricky part the 4 head bolt mounts? NO, the push rods hit the block and would need grinding the valley a lot, some of the early Mopar Pro Stock racers tried doing that swap on 383 blocks, it didn't work back then either down

Is it possible, just not feasible or practical ? Not feasible, my two cents

Even the motor mounts you can get around.

I would buy the better newer thicker Hemi blocks form World, FHO or Bill Mitchell up scope
