GM Performance Parts 350 H.O. Crate Engine - Project Humble Pie, Part II
The GM Performance Parts Bow Tie roller rockers utilize a shorter slot in the rocker body that increases strength by 30 percent yet still allows valve lifts of up to 0.575-inch lift. These are also self-aligning rockers that do not need a pushrod guideplate. The roller tip uses small guides on both sides of the tip to keep the rocker centered on the valve. View Related Article
