I can understand what you mean as I guess you would want the cars to have engines something like they had back then ? But no one can see the eng when the car is going down the track. Course when I see some Nostalgia cars that are mid 60's cars and they are running 8's that is also a bit misleading since they were no where near that fast back then. I guess the most important thing is the look should be right or thats what I think. I like it when they have to have the right hood scoops also as that helps keep the right look. I just don't like to see the rules get to easy as then it may start to get farther away from the Nostalgia look that the class is all about. Course myself I am just glad to see a lot of Nostalgia classes because its the type of racing I love. Ron
