Google 413 Wedge. Not HemI. You will see pictures with two four barrels on a cross ram intake as well as single four barrels. Edk
Yeah, 2 4bbl carbs on most, but I think you could get a center mounted single 4bbl too. At least on a Plymouth.
Both the 413 and 426 wedges could be had with the cross-ram duel 4's. they were developed for super stock drag racing.
