Well, I did find one thing out about the LS-6...IT'S GONE!!!!
After many hours of thought, I let the car go, as my ultimate goal has been to find a Yenko Chevelle...so, hopefully in the near future, I can give those pesky Buicks @ the Pure Stock Drags a taste of their own medicine (an A-body taking on the "other" A-bodies!). Simpson's COPO Chevelle has gone 12's numerous times, so 12's aren't a totally absurd number. I figure if the Buicks can go 12.40s with 8.5:1 compression, then what can I do with 11:1? Maybe I can con some of those "other" A-body guys into giving me some chassis tips

.
As far as the NSCA "Factory Pure Stock" class, it's essentially a 12.0 bracket class cause 11.99 and quicker requires a cage. But, I hope to have a car (Y-Chevelle?) that I can run both the PSMCDR & the NSCA events with, and give the fans an idea what these Supercars are all about!
I'm not sure about all the "hub-bub" with the Novas...all I know is that Jimmie J was PISSED! I saw where he got DQ'ed from the NSCA event the following weekend as well! I bet he was HOT! He told me the reason he couldn't run at the PSMCDR was that he had later aluminum heads on. He said they were GM Performance parts heads, which were a copy of the original head, but the exhaust valve was like .004" bigger and the exhaust(?) port was like <10 cc's smaller...something like that.
