Vintage Rochester Quadrajet 4-Barrel Carburetor 17057213 Chevrolet GMC Truck 350
The Rochester Quadrajet 17057213 specifically fits 1977 Chevrolet and GMC heavy-duty vehicles equipped with a 350ci (5.7L) or 400ci (6.6L) V8 engine and a manual transmission.
Because it uses a manifold-mounted "divorced choke," it will physically bolt onto and function correctly on 1977 to 1979 GM trucks using that specific remote choke setup.
Normal use wear.
