Richard: I think its a great idea. I also think there should be no problem with a stock spec JBL competing. I don't know why anyone would have a problem with it. Whats the problem? Are they afraid the JBL will out perform their cars? So what. It should with its more advanced suspension set up. Lets see where all these cars stack up and how they compare to each other.
My only thought would be to allow the Shelby 427 compete with a standard spec 427 either aluminum block or iron block. If thats the way the car is made stock/standard spec let them compete and see how it stacks up and other stanadard 427 cars stack up against each other and 351 cars.
