CFM 318 2 Barrel Carb ???

A hydraulic roller 318 or a pre 1973 318 responds pretty well to a four barrel though. The 1969 318 in question responds the best of all the eighteens to performance upgrades with the nearly 9.5:1 compression. A great place for one of the Holley 4165 or 4175 ThermoQuad or QuadraJet replacement 650 spread bore carburetors.
