265 hemi straight six
@valiantpatrol , here's what was posted with the photo.
"Slant six Chrysler experiment. This was on the Slant Six Forum and I believe was late model (Gen III) Hemi cylinder heads cut and merged together with a couple Gen I Hemi valve covers spliced together and custom intake/exhaust. I believe I only made it to mock up stage and don't know if it was ever a running project?"
