The 5.3 LS displacement engines were first produced in 2001 and continued all the way thru 2010. These engines produced anywhere from 295/335 to 320/340. Compression ratio also varied on their engine codes. 


Our 5.3 LS displacements are fully teared and cleaned with steam. All residue is removed, and painted if desired. All engines vary in miles but have no more than 150K. Our displacement engines are put back together to proper specs with all new gaskets and seals. If desired, accessory components can be powder coated.
