Carburetor rebuilds are obviously easier than engine rebuilds. Just consider the time involved: three minutes rather than five. What? We are, of course, talking about Redline Rebuild time lapses. In this go round, Davin Reckow rebuilds a Holley 4346, which can be found on Camaros, Chevelles, and Novas equipped with a 396-cid V-8 L78. This four-barrel helps the engine produce 375 hp and is a 780 cfm dual-vacuum-secondary carb, for those keeping score at home.
