The earlier post I started got pretty " Langdon Carter-Weber" intensive so I'll try soliciting info from you guys that run carter single bbls. I think the Langons setup is probably more efficient but Butt ugly!! Also I'm running the original 6 cyl because I want to be a little different. The Langon's are good for Some people but if everybody goes to them, I can see the modification becoming like the 350 Chevy crate motors in virtually every hot Rod that is built today. Viva the difference and lets keep the old ways alive along with the new technology.So what model carter carbs are you guys running? The Carter 4480-S was a stock replacement for the Rochester on '63-'67 Chevy trucks I understand. Any tips for tuning, linkage, air filters etc?
