Is there any hope of NHRA separating traditional Stockers...

Do not confuse NHRA rating and consumer SAE ratings. The NHRA usually took the original manufacturers ratings at face value on most VIN # cars. Example of say an L88 factory rated at 430hp actually made closer to 560hp. Compared to a 5.0(302) coyote at 425hp actually making 435hp and would take ported heads, cams and intake to make 560-600hp(500rwhp).

Now was the 08-later “package cars” underrated? Absolutely. The 425hp 5.4/2.3TVS was actually 605hp

As far as the Ford side of things a large chunk of the turnkey cars used factory part #s/castings. A huge amount of the parts are on the VIN car if you choose to build one from that and you can go to the Ford dealer to order the remaining parts(even the blower was a dealer installed option that would retain the factory warranty/emissions)
