Mopar now has conversion packages in stock for customers looking to install a 2004 or earlier model year 5.7L HEMI engine into an older car or truck. Available in both carbureted and MPI versions, these packages have all the necessary fuel, intake and electrical management system components you need. Packages replace the factory plastic intake manifold and drive-by-wire throttle body with a more user-friendly aluminum intake and top-feed, cable-driven throttle body or carburator, and includes all of the gaskets, hoses and clamps necessary to complete the installation.
