Gen-III LS engine swap

The owner of this ’77 Chevy pickup got tired of the performance and poor fuel economy of the truck’s 350 small block, and rather than rebuild the engine, he decided to replace it with something better. If there’s an engine better than a small-block Chevy, it’s one of Chevy’s new Gen-III small-block engines, which include the Vortec truck motors, LS1/LS6, and even the new LS2/LS7.
