Holroyd BBC Rocker Arms

There is no going back, might as well stop fantasizing about it. The options are ammend the rules to either allow non-OEM in appearance such as shown here or allow an aftermarket replacement; which is entirely what these Holroyd rockers are anyway.
If NHRA wants to inhibit RPM and performance by keeping a stock OEM rocker then thats fine, enforce the rules. If NHRA wants to allow racers a better rocker that doesn't break (yes, always at the wrong time!), then allow Holrod are Crane, it really doesn't matter since neither look or perform as intended from the OEM.
And I believe shaft rockers should be where shaft rockers were placed by the OEM & stud rockers where placed by the OEM.
