I plan on doing the Vintage Amr500 kit with the Solex 34PICT3. I was wondering if this is the most efficient and powerful carb for a downdraft application? I plan on doing the Vintage kit with the Supercharger cam and a rebuilt 1600cc. I don't want to lose power because I'm going with the vintage kit and Solex 34Pict3 over the sidedraft. Thanks!
