Now that this "bad policy decision" (.527 cam) has been allowed to happen and for decades, how would you "right the ship"? In the case of shipping weights, nothing much changes. Maybe the class and index but not the engine's ability to make power. How would/could they "fix" the HP factor? Would you agree that the combo should get a HP reduction? It's not like changing out one cold-air hood for another.

I get that and did know that, i was just referring to the debate as to why the Pontiac was able to run it compared to the Camaro, which was an actual car. Since the Pontiac was a "paper car" it was allowed to run the LT1. The Camaro is not a "paper car" so why is it allowed to run an engine that was not offered with that year and model???

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:

So the 69 Camaro 350 255hp cars get the cowl hood back?

Before NHRA took it away they were allowed on those combos since 1969

Besides changes in shipping weights has NHRA listed a form for the deletion of engine combos and the refactoring of engines some where? Similar to what they do with end of year HP adjustments. Good Times

Ford did not submit the .527 cam to NHRA as a Legal replacement cam for the 67-70 Shelby GT 500, the Manufacturer did.
NHRA made the decision to allow all 428CJ cars to use the cam.

Shelby American sales brochure listed quite a few options on this car other than a camshaft.

Have a great day, could be your last.
