The K5 Blazer received a redesign in 1973 which ran mostly unchanged until 1991. GM must've known it had a winner as they applied the old adage of, "If it ain't broke, don't fix it." While the Blazer is plenty capable in stock form, you can take yours to the next level with a bolt-in LT swap and a variety of parts from us to make it more capable, on-road, off-road, and anywhere in between.

The GM LS engine has quickly become the high-performance standard in the performance aftermarket. Holley and Hooker have partnered together to offer the most versatile and complete LS swap kits on the market so you can install the GM LS engine into your favorite chassis! These swap kits have been engineered by Holley for a easy bolt-in engine swap where all the parts work together as a fully engineered system.
