There you go 396 has different spec than a 1970 402 this is reason for a DQ. If this was anybody else it would have been an auto DQ. Once again different rules for different folks

The 1970 is allowed a 1.88" exhaust valve, the 1968 is allowed a 1.84" exhaust valve. The dome volume and chamber volume is the same, the dome height is lower for 1970. The other difference would be the intake, if he was running the 163 intake. In 1968, the plenum divider cannot be cut, in 1970, it can. Yes, there is a 0.030" difference in bore size. Given the car has been campaigned as a 1968 for the most part, it probably meets those rules. I don't think Clark Holroyd has been cheating up his 396 all this time, using 1970 402 specs and running it as a 1968. My point was, you can't run a 1970 in AA/S. So if you want to run the car in AA/S, run it as a 1968, there is no disadvantage. Most are running the 401 head and the 359 intake. So the only possible advantage to the 1970 is the 0.030" bore size gain, and the 1.88" exhaust valve. Well, the cubic inch gain from a 0.030" bigger bore will be minimal, as will the unshrouding of the valves, which would be entirely negated by the 1.88" exhaust valve. Again, not seeing a real disadvantage to the 1968 combination if you want to run light and go AA/S racing. Besides, it's the only one that fits the class.

When you see a friend get DQd for class at Indy because he accidently had "ONE" TRW pushrod in his Cobrajet stocker you tend to lose respect for NHRA tech

And for the record, the 68-69 Nova taillights are a little shorter than the 70-72 taillights so the interchangeability is not there without modification to the taillight panel.

At the New England National Open last year, everyone's class/combination was verified during the tech in process. It added about 2 minutes or so to tech. No big deal.

OH, they would have to pay someone to come up with the program and maintain it as well as administer it at the races. Administering it at the races would require another step in Tech. They can't afford to do that when it is to the racers benefit to learn how to class his own car and fill out the paperwork correctly. They can't afford to be responsible for anything like putting a car in a class. Having that step in Tech would imply responsibility and possibly leave them open to law suits. OH, yea now I remember that could be the reason the process is the way it is now. Someone sued them for putting them in the wrong class & it put a financial burden on them. The last thing that should happen is a financial burden be put on the racer.
