The Chevrolet K1500 Pushrod is located in the valve train at the heart of the truck. It turns the rotary lift of the block mounted cam into the up and down action that opens and closes each cylinder valve. The steel rod connects the lifter to the rocker arm in the overhead valve configuration that was applied for decades in small block V8 production. This approach has served Chevrolet small blocks for a long time. Oil is also channeled by each Pushrod to the rocker tips for lubrication. By riding the cam lobe, it delivers timed lifts so fresh air fuel can rush in while exhaust escapes after combustion, which maintains compression and power. The early iterations applied basic stamped rocker arms. The later engines stuck with the same basic Pushrod layout but benefitted from the use of stronger alloys and hydraulic lifters that take up clearance automatically, reducing noise and wear. The excess heat, high rpm, or widening lash can bend a Pushrod. Pushrod bending causes ticking, misfires, and valve float that robs horsepower. When bent, the faulty Pushrod must be removed and replaced before it damages springs or allows contact between the piston and valve. Despite these drawbacks, the configuration permits the K1500 engine to set its cam low in the block. This results in reduced overall height, which makes servicing less expensive than with overhead cam systems. Like major Chevrolet small block engines, drivers of the K1500 still enjoy this attribute today.
