Lots of these setups are out there, but very few of them work as well as an original 1-carb system. Dual carbs are mostly eye candy, unless you're dealing with a highly-modified race-only engine. You'll encounter flat spots, backfires, and generally very twitchy low speed and midrange performance, to get a slight improvement in top-end horsepower. It will take a different camshaft, valve and head work, and probably a modified spark advance curve, plus a matched set of the correct size (small) carbs to make a dual-carb/header system work almost as well as a stock setup. Large dollars and LOTS of hassle!
