Holley’s Tri-Power Carburetor system is legendary in Chevrolet circles! They were the ultimate power statement when they came factory on cars like the 1967 427 Corvette. Now you can have the same look on your SB Chevy! Perfect for muscle cars, street rods, classic hot rods, rat rods, trucks, and more! Cruise around economically on the 350 CFM center carb, and when you decide to step on it, the two 325 CFM outboard carbs kick in for head-snapping performance! Choose from either the dichromate (300-521) or shiny carbs (300-522).
