It looks like the spreadbore marine intake..... 1.25 inches
taller than a typical stocker. Boat guys use them, most
dirt tracks wont allow them.

You see them in really nice shape selling for $100-125. Other than marine use, the only attraction is if someone is trying to make a motor that looks original but has a little more.
Never saw this part number claimed to be as good as an aluminum manifold.
