Carter 383 2bbl for SL6

MVH......thanks for the reply to my querie on the Carter two throat for the Super Six. Currently I am running a factory cast iron Super Six w/ an OEM carter 2bbl for a 318, I purchased from a guy in Kansas for $120. He bought from a military auction. I believe CFM's on it are 280, runs just fine. The 2bbl I have, that I found is the Carter OEM 2bbl carb for the 361 and 383 engines. Looks like a 4 bbl as you look down at carb from air horn down, but a 2bbl from the side. I also have an OEM factory SL6 aluminum 2bbl intake manifold.
