I don't often respond to much on this type of thread, but please let me explain. The reason for a carb change is most racers are having work done by a professional on their Rochesters, thus gaining an unfair advantage over everyone in the class that isn't. You buy a box stock legal Holley and we can check it with our gauges, and also you as a driver can use the same carb if you move up to Street Stocks or Sportsman. The economy header idea was implemented to save the racer extra work and money. If you buy a good set of center dump manifolds (you will if you want to have an edge on others) have the exhaust extentions made you will have spent more than an economy set of headers cost ($70 to $100).. The track tire idea was to stop certain guys from outspending others to get a better tire, to the tune of $120 per tire. That's crazy for most in this division. I am trying to come up with something that costs the racer say $50 or less, and try to get a point fund bonus out of it as well. I am not in the tire business, I am in the racing business! Any other questions feel free to call me at 607-533-4118.
Thanks,
Dick
