Pure Stockers New Camshaft Rule !!!

[Dwight Southerland]

As a matter of historical fact, when NHRA allowed any stock appearing valve spring, it was shortly followed by aftermarket steel retainers, ceramic lifters, tool steel lifters, oversize pushrods, oversized studs, and now, roller rocker arms. And stockers than run 8500 rpm in the lights. I don't believe that is what you are looking for with Pure Stock.

This was well said.
My mind has been spinning taking in all the feedback....Springs, Cams ...!

Bottom line, Got to keep the rules the same.
Keep Pure Stock rules as they are. Need discipline. No changes!

More Valve Spring will allow for more radical cam science.
Someone posted that there is a record of every spring on cars.
Ok let's use it. If IHRA needs a Spring Tester. I will Pay for it.

Think the real issue; Tech and Racers need to figure out how to make Tech easier.
Some have posted harsh opinions about PS. That we are not real Stockers.
Yet we are running on the old rules before Pandora's box turned Stock into Super Stock light.
Not to dirge today's Stockers, in 1985 few Stockers could run on a Super Stock index's.

I have magazine articles when Junior Stock and FX and everything got reorganized.
Stock became absolutely Pure Stock to the correct option, facia or emblem on the car.
Minor technicalities got you busted. Today much of this has been relaxed.

1974 the rules changed to allow Blueprinted cams.
Because racers were regrinding their Stock cams during the Real Pure Stock years.
Stock grew yet remained a tech management nightmare.
Stock Science morphing got what they wished for.
Now they are Super Stock light, far from Stock and way expensive.

IHRA had the wit to be different experimenting with new and old ideas.
Today's Pure Stock is using 1985 rules, growing with the same tech headache.
They added Crate Motors morphed into something unStock, again (my opinion).
But that was the trend.

Bottom line!
Pure Stock allowed me to get back into the game. So did many others.

Please leave the rules as they are.

A lot of the older, hardcore Stocker racers will tell you that the valve spring rule was the beginning of the end in Stock Eliminator.

There you go......The "KING" of dime rockets has spoken. Danny and Billy both said it and they have been around this game a long time. If the duration and overlap spec. does goes away at least keep the max spring pressure rule low to control the exotic and expensive parts from entering pure stock. Keep it low enough to control the parts used yet high enough to be fair for everyones combinations whateve that might be. Pure stock dosent need those crazy cams that stock uses today nor the 8000 plus RPMs. I remember when Cam Dynamics came out with their 7000 RPM plus grinds back in the "stone age". Valve springs would not last more than a few runs if at all when NHRA still checked duration and overlap. Some of you might not be old enough to remember Cam Dynamics and their square nosed cams.
It all comes down to finding a way to ensure that pure stockers will pass tech without diassembling the entire car.

Probably could make the same argument for "traditional" stockers.

Pure stockers could have light pistons,cut down cranks,bogus rods too.

True....and I have no doubt that some (not all) are like that. What happened to integrity !!!!!

Sure could!
That extravagant cost will yield little advantage.
But it will open that box if the Spring Rule is changed.

Back when stock had pure stock cam and valve spring rules my Rimac spring checker was the most important tool I had.

Well said Terry. I still have my CD 302 cam. It saw little usage as valves springs were lucky to last 2 passes. Plain nightmare
