In this work we present an extension of the Standard model as a local gauge group SU(3)c x SU(4)L x U(1)X embedded in SU(3)c x SU(4)L x U(1)Y0 x U(1)B-L gauge group. The U(1)Y0 gauge symmetry is introduced to obtain an anomaly-free three- generation model without exotic electric charges .A minimal scalar sector is considered with two Higgs 4-Plet representations of SU(4)L and a singlet scalar The 15-plet gauge bosons of SU(4)L contain two new neutral bosons which mix with Standard model W. The (B-L) charge is assigned to U(1)B-L gauge symmetry so thatSU(4)L gauge bosons do not contain bileptons. The model is analyzed for mass spectrum of Higgses, fermions and gauge bosons with results similar to an economical 3-3-1 model with two Higgs triplets. In 3-4-1 model both 4-plet scalars contain two neutral components each.There is no lepton number violation in 3-4-1 case.
