Holley Performance Products and Hooker Headers are proud to announce the release of their GM LS swap products for the popular 1973-87 2WD GM C-10/20 pickup trucks. It is important to use components that are designed to work together to ensure a trouble-free install that provides optimized drivetrain geometry and component clearances. Holley and Hooker have partnered together to offer comprehensively designed complete LS engine swap products that do just that. They have made it possible to purchase a system of components that offers compatibility far beyond what is available when using components from mixed sources. With many header, material, and finish choices, Holley and Hooker have everything you need to drop a GM LS engine into your C-10/20, your way. The swap components include engine mounting brackets, transmission crossmembers, headers or manifolds, exhaust systems, exhaust adapter pipes, oil pans, and an accessory drive kit. The individual product text and high-resolution images can be found on the C-10/20 LS swap page.
