I could've had mine punched to a 71 for my 6.0 and been legal per the rules.
That's the case here too. Not many people here maximize what the rules allow though. I don't see any harm in asking to take a look since this guy kinda came outta nowhere this year. In a small outfit like this competitors checking out each others trucks is about all you have for tech. The track just checks weight and hitch height.
But I will say this: one time a few years ago my dad entered mod class and stock class, just to get more hooks and support the pulls. When he showed up at the staging area for stock class, a few guys ran crying to the track owner and got him kicked out of stock class just because he had pulled in mod class earlier. No tech, no accusations of cheating, just kicked him out to shut them up. That's the kind of outfit we are talking about.
