Unless you or someone you know is a wizzard at multiple carburetors, you're leavin horsepower on the table. Multiple carburetion is always better than single.......IF and ONLY if they are in synch and tuned correctly. This is why over 90% of the time you see single carbs winning out. It's almost a lost art in a way. Probably one of them new Holley 870 vacuum carburetores would be good on top of sumthin like maybe an air gap.
