Thinking outside the box

Big Dummy posted some really impressive numbers for a head I don't recognize.

The block looks like a Hemi block (top row of stud receiver bosses) and the shape of the ports look like 426 Hemi stuff, but the pistons don't have that HUGE Hemi dome.... Maybe they're low-compression blower pistons???

Fill me in, please. I'm lost....:angry7:

PS I'll bet dollars to donuts it won't bolt onto my poor ol' 360 Magnum, though... lol!
