Webers- - - - -good choice! I raced a Datsun 240Z with three DCOE 40 Webers on it, but it was an all-out competition setup that never hit the street. I'm also planning to build up a Triumph Spitfire with a GM 2.8L V-6, and I'll use a single Weber 48IDA downdraft carb on it. Most of the guys on this site are locked into Rochester or Carter 1-bbl's when they go with multiple carburetion, so they end up waaaaaay over-carbed. The oldtime 235 Corvette 3-sidedraft setup was effective, but very maintenance-intensive, and a working-condition one is outrageously expensive now.
