I know that, and most VW guys know that but what I'm concerned about is if a non VW competitor looks at the engine code stamped on the block and it isn't a 10:1 motor would they have ammo for a protest? I wouldn't think so but what does the letter of the rule book say? If I read the above statement, I can't swap in 10:1 pistons if its a GX or JH stamped motor. It sounds like I can take whatever motor assembly that is already 10:1 comp and swap it in there since the spec line states 10:1 is authorized.
I know its trivial but in this thread: https://improvedtouring.com...ad.php?t=20471 there is quite a bit of discussion of whether he can swap out his 16v for a 8v. So obviously someone reads the rule one way and others read it another. I just want to make sure before I spend the money.
