Just because they have cars in our class that do not belong, it doesn't mean we need to make it worse. Doesn't matter what year it is, either, that's no excuse to keep screwing up the class.Agree.

I can do things with a roller rocker that cannot be done with a factory rocker. Especially with the advent of CNC machining being common. You can build the rocker to give the correct lift at peak lift and still do all sorts of things to the lift curve. I'm not going to go into that with anyone, I'll just say you should take a look at the old Crane "quick lift" rockers, or what ever they used to call them. There are other things that can be done, I won't let those secrets out either. Let's just say I had a long talk this week with three guys who know way more than I do, and all three agreed. They've got about 120 years experience going fast and setting records between them.Interesting. I would like to learn or understand more of that.

Sure it will, we'll have stockers turning as much or more RPM that Super Stock cars turned 20 years ago. But stockers are limited to heavy pistons and rods, and factory cranks, Super Stock is not.. Sounds like a good recipe for disaster to me. Some engines that can't stand the RPM may fall behind.

Stock is not allowed to have radiators that are not original size for the body, nor to have radiators that are not made of the original material. You can't put an aluminum radiator in a 69 Camaro for example.

Stock is not allowed to have through the firewall roll cage bars.

Stock currently requires original seats, I'm not sure it's a great idea given we're approaching 135 MPH with traditional combinations in fast classes.Agree as well.

Stock has an open valve job rule I already mentioned, not a good idea, but not a reason to add to the escalation.

Stock is not allowed to modify the rear frame other than connecting the roll cage.


The solution to breaking parts is not to keep asking for more aftermarket parts. The solution is to find out how to stop breaking that part. Every combination has limits, when you reach the limits, that's it, either change combinations, or switch to Super Stock. Otherwise, Stock Eliminator will BE Super Stock before long.Point well taken.

I truely believe that alot of these rule changes in stock from the open duration on the cams to valve jobs to any springs and spring pressures are due to the lack of qualified techs to police these rules. Policing rocker arms is not an issue obviously but I think all the other rules have just lead to this as the week link for now. Which is what you are saying.
