Building or rebuilding a GM small block? These push rods are a key piece of the valve train puzzle. This 16-pack is made by Enginetech (sold through LowPricedAutoParts) and fits a range of popular GM/Chevy engines: the 4.3L 262, 5.0L 305, 5.7L 350, and even the 6.3L 383. They're built to be strong and durable, handling the high stress inside your engine so your valves open and close like they should. Good push rods mean consistent valve timing, which translates to smoother running and better performance. Whether you're doing a repair, a refresh, or a full-on performance build, don't cheap out on the parts that connect your cam to your valves. These are designed for a straightforward fit and reliable operation. Always double-check compatibility for your specific engine setup, but if you're working on one of those classic GM V8s, these push rods are a solid choice to get your ride breathing right and running strong. It's one of those 'while you're in there' parts that can make a real difference.
