Torque Plate, Aluminum, Big Block Chevy, Sonny’s 5″ Bore Spacing, with Inserts and Spacers
All of our torque plates are 2″ finished thickness, made form US-source manifold-grade 6061-T6511 Aluminum extrusion. We press-fit hardened steel T-Washers at all fastener locations for wear resistance, and match the factory bolt boss height by either countersinking the plate or providing custom-length heavy wall DOM tubing spacers, so the actual fasteners are used during honing. If you are using an aftermarket block or head, check with us to verify measurements so we can get you what you need for a bolt-on solution. Use the Add to Cart function to contact us for current lead times and to order.
