On the 12.12 I bet that's it.

As of Oct 1969 the D/S=9.00 class record was exactly 12.12, set in Aug 1969 by Robertson's 67 Z28. What are the odds?

Charbonneau lowered it to 12.06 for E/S=9.00 in feb 1970.

On the cam duration, I often wonder why, even in the late 1960s when cheater regrinds became legal as long as they met "advertised" duration- instead of using that goofy standard, why not degree them to factory spec on teardown at .050 lobe? Ok most people didnt use that standard yet, but FoMoCo had used .100 lobe specs since 1957. The OEM's all knew those numbers, you had to know them to grind the OEM cam!

That's a lot easier to measure than "advertised", a lot more meaningful, and would have kept the cams a lot closer to true stock.

But that's all history too.

As it is, when Gonkulating these old NHRA combos, I have to try to guess about how much more .050 or .100 duration they could fit in a regrind and still meet spec for advertised duration, lift, and springs.

Agreed on "bombing" the record, although I guess that would only affect eliminations, not the class winner? I always correct for weather, just as important as altitude. Seems that could have been done to correct records back in the 1960s even. Of course even tail or headwind will affect trap MPH but that's hardly ever recorded.
