Actually, the classes themselves were created to stop all the crying. The cars came first...

Re: COPO, Drag-Pak, CJ II, (FX) Secrets
Here's another one:
"Aluminum center section permitted only on vehicles that were originally equipped with same." In other words, a "stock" CJ II center section is not allowed in another Ford CJ 1

More...
"Porting, polishing, welding, epoxying and acid-porting prohibited. Combustion-chamber modifications prohibited. " I don't see where CNC porting is allowed

Re: COPO, Drag-Pak, CJ II, (FX) Secrets
I guess the argument has now turned to interpreting the rules?
Every turn-key late model factory car came with a 9" rear and aluminum center section. The 2008-up rule came when racers started converting the factory cars to their production version around 2015. Factory ported heads were in the guide before 2008.
