Crate Motor Class

>>>>>"If that is not SPEC then what is?"

Read the rule book section on cylinder heads used on a Top Fuel motor. NHRA dictates LOTS of specifications that cannot be varied from. There is no Rat Motored car in Top Fuel, no wedge combustion chambers, and no variation on the type and size of superchargers that are allowed in that class.
It is a "SPEC class. I. E., the "specififications" that are legal for that entire class of cars are spelled out for you, and if you want to run a car in that class, you build what they dictate. Period.

"Ingenuity in Action," which USED to be one of NHRA's favorite mottos, died in its sleep, and was quietly shoved under the carpet many years ago.

In Stock, they do dictate some specifications as to what is allowable for YOUR chosen motor, such as what constitutes a "legal" valve job... (along with other across-the board rules that don't, as far as I'm concerned, qualify the cars as "spec" cars because they can be performed on any car you want to run; a Chevy, Mopar, Ford, AMC, etc....)

If they said, All Stock Eliminator cars have to run 23-degree heads, " THAT would be a "SPEC CAR" type of ruling

I guess the best example I can think of RE: SPEC cars, is the NASCAR "Car of Tomorrow" that has no room for individuality in the engineering left to perform; it has "SPEC" everything, no matter whether it's a Toyota, Chevy, or, whatever. "Cookie Cutter Car" comes to mind....

NHRA Stock Eliminator has always dictated specifications for the individual (Stockers) cars, and those cars have maintained their mechanical autonomy (at least, to a large extent), because the bulk of the "specs" they must adhere to are the specifications that are pertinent only to that very car. Not a whole lot in the rule book that's trying to make a Street Hemi and a Pinto W/SA car into the same vehicle.

That is my own, personal conception of the term "SPEC" car....

Your mileage may vary.
