Like Chevy's 'big' block 348 and then the later 409, Ford's 'Y' motor had a similar combustion chamber design........................in the piston. Both had cyl heads where the business side were virtually flat. Kinda like a diesel cyl head on the valve side. The actual 'chamber' was in the pistons. Very odd really, but both GM and Ford thought this was a great idea for larger displacement engines in the 50's. I do wonder who copied who then......................

Chrysler, on the other hand had already had the 'Hemi' in production, even though early motors were very small displacement was waaay ahead until Chevy's small block offering.
