The SBC Stamped Long Slot Rocker 1.6 Ratio from PROFORM is designed for serious small-block Chevy builders who require precision in valve train geometry for both street and strip applications. This product is ideal for refreshing engines such as the 283, 307, 327, or 350, offering a cost-effective alternative to forged rockers while ensuring reliable performance across a wide RPM range.
With a 1.6:1 ratio, these stamped rockers effectively multiply valve lift and duration as intended by your cam manufacturer, optimizing valve event timing and cylinder head flow. The long slot design accommodates variations in pushrods and geometry, while the lightweight construction minimizes valvetrain inertia, allowing for higher safe RPM limits compared to heavier forged designs.
These rockers are perfect for stock-replacing service on original small-block Chevys and for budget-conscious builds where the cost of forged rockers is not justified. They are compatible with OEM pushrods, valve covers, and standard 7/16" rocker studs found on classic SBC heads, requiring no adapters or modifications for installation.
