Edelbrock Valley Plate (GM LS1 & LS6)

This as cast aluminum plate is intended for use on 1997-2004 GM LS1/LS6 engines and similar GM Gen III engines that have been converted from EFI to carbureted set ups. The plate includes a breather boss that will need to be drilled and tapped by those retaining the stock LS6 breather configuration or for LS1 users looking to convert to a LS6 style. Will not work with LS2, LS7, LSX or any other GM GEN IV engines.
