When I started trying to count the potential classes it looked like there was going to be an open class, one for Prostock, a prostreet, a superstock, a heavy superstock, a 12.0 index and a bracket class. I'm for anything that will bring more racers to the track to race and not just watch.
As far as what Dieselbeef said, sure there are going to be faster trucks running an index, you had better have something that can run the number or a bit faster or there is a good chance you will not win. If your truck can't run the number drop down a class and then you will be one of the trucks to beat. If you run an index on a protree either .4 or .5 the race is pretty much on the tree if both trucks can run the number. I like the .4 protree since I can't redlight on it, I can on an .5 which is probably why it should be used. A lot of driving involved in index racing. It isn't just mash and go and you also don't have to wait at the line for 5 or 6 seconds when you are racing a much slower truck like in brackets. You can sucker a quicker truck into breaking out if you know your truck and what it runs. I grant these classes favor the trucks that can switch tunes on the fly like the EFI trucks. That is a huge advantage. Also allows you to fine tune the trucks to really hit the number.
Index racing makes the most sense, don't have to get so crazy with the rules, the guys can pick the class that makes them competitive. And it would be the cheapest for the competitors. I started drag racing in 1960 and have watch a multitude of rules changes and growth. It has never been easy. As far as I'm concerned when all the electronics took over and pretty much took the driver out of it, took most of the fun too. So no electronics please.
Again, good luck with the race, wished I were 2500 miles closer, I'd still be 500 miles a way, but I'd love to come and race.
