Okay, makes more sense. Why couldn’t they just say running the same engine specs rather than “engine family”.

The FE engine family is confusing enough with all the different variations. There are numerous combinations that could be in the same class. Now I see how this could help with the average for each because hardly any two 428 cars are running the EXACT same combinations.

What effect would bringing back the factory valve spring rule have?
Would this not simplify tech and negate some of the advantage found in cylinder head and intake advancement?
