I appreciate the idea, WIllis, but the short answer is no. 🙂 We will not alienate anyone who modifies their car in the Modified classes. That is exactly what they are. The argument came up about having LS style engines and SBC, etc installed....the counter to this argument is that recently there have been factory Buicks with the LS style V8's installed, and also the mid 90's Roadmasters with 5.7L "SBC" engines. So, the argument that Buick-only engines in Buicks is moot.
Also, you can't help but notice the wildly popular LS swap phenomenon that has swept the community in the last 5-10 years. My gut says that the modified classes will be seeing MANY more of these as time continues. We cannot turn our noses up to this, ESPECIALLY in the modified classes where it is literally in the meaning of the word.
I love me an all-Buick Buick, but we have to have open arms to changes. If not, this is what kills clubs, and has been killing clubs.
