    Most of this is good, except I think we need to weed the cars out that have motors set back further than #1 spark plug and the underslung cars, Also I think it would be great to go to the American Racers that Sayre run for a tire that way you have those cars that can come run here as well and there is a lot of them and I’ve talked to some of the guys already and they like that idea. Need to specify more on the rear end like 4link or 3link, and allow the 180 degree header? thats all I really have, I just want it to be where we can run at multiple tracks because Nashville has the All American 400 weekend and Sayre has The King of Dixie weekend and then theres the Snowball Derby. But really happy the place is being opened again, anything is better than nothing.

  2. shawboy16

    Also try to have a talk show on Sunday nights that speaks to some of the racers and talks about what happend at the track that weekend and what is going on the next weekend and also have the races rerun on tv on a local channel sometime during the week!

    I agree with running the American racers, it makes it more affordable for everyone. I disagree with underslung and engine setback further than #1 sparkplug. I think 3link or 4link should be legal. No Alum heads. no 180degree headers. no dry sump. I look forward to racing Friday nights at Huntsville again, Thank you.

    Friday or Saturday night?

    In addition, I would like the use of the cone during a caution. They would take a cone and sit in the middle of the track and as you came around under caution you could either take the inside or the out side lane. Every restart was double file. It made it more exciting and was just fun to watch. Thank you, Alan Callaway.
