Slant 6 Pak?

If you're feeling lucky, Clifford sells a 3X2BBL Weber manifold. Not cheap and good luck getting it from Clifford. There is one on Ebay right now from Australia. Item number 130174085561 if you want to check it out. IMHO these are great for an EFI conversion but a royal PITA to set up and get running right with carbs. Two are hard enough to get right.
