69 Chevelle AA/SA 10.04 at 125mphat Spring Nats

The 8.49 has always been rounded to 8.50, and as recently as a year or so, when I looked, NHRA policy was anything over 0.25 pounds was rounded to 0.50 pounds for classification, as written in the rule book. I was looking at buying an already finished car a couple of years back, and NHRA told us in no uncertain terms that the 427/425 in the 69 Chevelle was 8.50 natural with the automatic, and we could not put the car in AA with an automatic.

By absolutely no means am I complaining, I actually hope that it is correct for the class. The 69 Chevelle is my chosen combination to be the companion car to the 69 Camaro Kevin Cradduck and I have campaigned since 2007. The only engine we couldn't share between cars is the ZL-1 we have. So, yeah, I'm hoping fervently that a cast iron head L-72 gets rounded DOWN to 8.00 instesd of up to 8.50, because I'd like to be able to run AA with either transmission. I'd much rather be able to run A or AA with both transmissions.
