Next on the to-do list was a set of roller rocker arms. These blue aluminum roller rockers from Ford Racing work well as do the more cost-effective die-cast High Energy rockers from Comp Cams. Run with the FRPP 1.73:1 ratio roller rockers, the 460 produced exactly the same power. We’ve seen rocker swaps net 12-15 hp on other applications, but on our mild 460, they didn’t offer any power over the factory rockers.
