Why did nhra change the cam and valve spring rule in 1985?

But anyhoo, I agree... get that party started, Mr. Bell! I'm questioning my sanity, but for some silly reason, I've been daydreaming about building a "traditional" Stocker motor for the Volare.

I dont have any say so any more. Im afraid its up to the racers to decide what they want and to really push for any changes IF they see someway to reduce the cost of running over a season of racing. Even then the NHRA dosent listen very well. Get used to what you have. I see more oil downs and diapers in your future if you want to remain competitive and be one of the fast guys. .

Ha-ha-ha...YOU'VE GOT THAT RIGHT!

How pathetic...

If you check out the rules for IHRA pure stock you find a class thats in line with the original intention of stock eliminator. A person can put together a competitve car for a lot less money. If rules are enforced theres no problem. As far as reliability, while I don't race as much as most, my 327 has been in the car for 5 years without freshening and only minor repairs and still runs the number. Pat

You guys need to get a TIME MACHINE...
They make the rules as you go along.

The problem is that they change the rules as they go along. Instead of ***** footing around, why not allow roller cams to match the newer engines with roller cams and also fuel injection while we are at it. Did I also miss crank trigger?
The rules in stock, should be stock and not with all the after market parts that don't belong. I like it to see someone squeeze out HP with limited parts to their disposal, with controlled regulations and not just put in (full advantage) after market parts that they find on the shelf. I'm sure most of the time, NHRA will accept parts, if we pitch a bitch enough about how hard it is to get originals even if their are plenty of those originals still around.

James, I can see that you need a good "balance job"! I think about 2oz of lead behind your right ear would be a good start!

I wrote the rules for pure stock.....the problem is the enforcement of the rules.

NHRA doesn't want to do their job on policing rules and for that matter what we pay for from them when we buy our memberships. NHRA is streamlining for their benefit not to have to enforce rules that should have been kept up with, like valve spring pressures. The cars in stock would not be running 1.0 under if the valve spring pressures where set to factory spec. for sure. The valve spring spec on my 302 engine was 96 lbs on the seat and 204 lbs open pressure, no way could you get the motor to 8k rpm. Now, they are changing gears at 8200 rpm.
My vote is to go back to enforcing an across the board valve spring pressure so that you have to use stock (buy in any auto parts store) lifters again.

An across the board number is no better than what you have now. Heavier valves need more spring pressure to control the valve. If you went back to using the specs that would be more equitable. But still not perfect.
