intake manifolds

  1. Challenger Performance Mods - Engine - 5.7L HEMI
    Has anyone installed a Mopar 392 intake manifold onto their stock 345 cid engines? I am aware that you need to install the MSD window switch in order for the new manifold to switch from STR to LTR at 4,800 rpm with the exception of 2013 and newer models.
