421

[Betojrz80]

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!

35mm are ok

35’s if there are tight hill shoots and spots where you need more throttle response. But if it’s mostly wide open dune cruising, drags, and hill shooting the 39’s will dominate.

Thanks for the info.
