MM, you can sugar coat it and justify it all you want, but the bottom line is that you are custom making a part with with non stock components and dimensions, and the express intent of giving yourself more performance than you can get otherwise.
You can tell me that other replacement parts don't exactly match the original part all you want, but the bottom line is those parts would fail a protest as well.
You can tell me that it's harmless, and that the rules suck and need to be changed. Actually, you have told me that*.
And have told me that it's not fair, because you're getting a worse shake than other cars.
Those are all rationalizations, I'm sorry to say, to cheat.
You said my example didn't help. Of course it didn't...it was another example of an illegal part.
The bottom line here is you are drawing a line in the sand where YOU want to. Others in this thread have suggested methods for you to have your cake and eat it too...legally. But you're not interested.
I'm sorry to say it, but from a outsiders point of view, it calls to question the overall legality of your car. Did you decide to just put a cam in instead of the traditional approach to save yourself money and time, bearing in (your) mind that replacement cams aren't exactly the same as a stock cam in some cases? Or pistons? etc etc.
Sorry if you think I'm being rude, but ......
