Show original supplier description
The Scorpion SPN1047 is a set of Race Series roller rocker arms engineered for Small Block Chevy engines. Constructed from CNC-machined 7000 Series Aerospace-Grade aluminum, these rocker arms offer durability and performance. They feature a 1.7/1.6 ratio and a 7/16 stud mount for secure installation. These rocker arms boast a full-body design with a 1.6-inch fulcrum width, providing ample valve spring clearance for springs up to 1.625 inches in outer diameter. The rollerized needle bearing fulcrum assemblies and wide contact roller tips contribute to reduced friction and improved valvetrain efficiency. The striking blue anodized finish adds a custom look to your engine build. Each set includes thick-walled 4140 steel polylocks for reliable operation. Designed for Small Block Chevy engines, specifically those in the 265-400 cubic inch range, these rocker arms are a direct upgrade for performance enthusiasts seeking to optimize their engine's valvetrain.
