Hooker Blackheart is pleased to announce the release of our new Gen-V LT engine swap headers for the 1973-1974 Chevy K10 truck chassis. These headers are designed to increase engine performance and provide the best component and ground clearances available for this application. They can be used with all GM automatic transmissions, the venerable SM465 manual transmission, and NP203, NP205, NP208, and NP241 transfer cases. In addition, they feature 100% 304SS stainless steel construction, 3/8" thick flanges, and formed-merge collectors with one O2 bung in each of them.
