The demands placed on a road race carburetor are quite different then most other types of racing. The carburetor must perform flawlessly in a wide range of car motions. These motions can cause problems for a Holley® carburetor if it is not set up properly. The drivability of a carburetor is as important as the power it will make. Chuck understands this and has put together several road race designed carbs.
