I’m coming out with a 421, The engine is done. I got a dune port on it. I’m trying to figure out what carbs and size to go with. I want to have fun at the drags, but dune it too. I had some Vito’s 35 mm on it before the build, but I’m might put the Vito’s on a other shee I got. Ant info would be helpful. Thnx!
