This rocker arm and shaft set are blueprinted by Ivey Engines specifically for Formula Ford 1600 use. Includes profiled rocker arms, rocker shaft, separator springs, washers, and hardware. Mounting bolts are not included.
- Rocker arms profiled for SCCA maximum lift (0.356" intake / 0.358" exhaust @ zero lash) with stock Ford camshaft
- SCCA-legal billet aluminum rocker pedestals for greater strength
- Dyno tested by Ivey Engines prior to shipment
Note: Because of the high lift provided by these rocker arms, this assembly is for use only on engines prepared to SCCA Formula Ford specifications. Maximum permissible cam lift (measured at the pushrod) is 0.233" intake / 0.234" exhaust. Your valve springs must allow a minimum valve travel of 0.356" intake / 0.358" exhaust without going into coil bind. Higher lift cams or less available valve travel will lead to damaged parts!
