Is it rare Poly 318?

No, the 277,301 and & 318 will not accept a HEMI head though other engines can. In example the old Firedome engines will take a HEMI head easy. It is much like the "LA" and "Magnum" series engines that need abit of everything from the block up.

Thanks, rumble, forget to clear that up since I was going into the '50s.
