I have a 1953 Dodge 4 ton B4ya series with the 413 twin carb /dual exhaust/ "Nickel Moly block-- says on the side of the engine, factory tach drive distributor/air brakes ect. All restored to as new.413`s were only used in the dodge trucks from 1953 to 1956 in only the 4 ton "Y" series trucks. Also in some marine applications. I have several other displacements of this same engine. They are quite rare! I like this 54 Dodge!
