It's not like changing out one cold-air hood for another.

In the early days of Super Stock, lots of stuff took place between NHRA and the factories via a phone call or a letter.

My understanding is that a version of the 427, C8AX-6250-C hydraulic camshaft, with the adjustable 1.76 rocker arms with 0.527" lift was approved by NHRA in 1968 for use on the Stock Eliminator 428 CJ Mustangs by a letter issued by Ford.

There was a lot that took place behind the scenes, including the so-called, Canadian, SK cylinder heads, developed by Bruce Sizemore and as shared on the following link:
