For sale 56 dodge royal

Yup, that's a Poly not a Hemi. The block is the same as a Dodge Hemi from that year, and they can be switched over to hemi heads (with a piston change) if you can find them to make it a hemi. But in its current form its a Poly. The naming of it is kind of misleading, because depending on the year ('55 or '56) they called both the hemi and the poly a Super Red Ram.

My g/f's '55 Coronet has a 270 Poly in it. Great engine, shares all of the same parts with the hemi except for the pistons and heads/valvetrain.
