Schubeck lifters

Further, it is nearly impossible to set a spring pressure rule that does not have a disparate effect on various combinations. What works for one engine and allows it to reach maximum potential will not be nearly enough for others. So, who do you handicap, and who do you give the advantage to?

In any event, making a seat pressure (or any spring pressure) rule will only result in people having to spend a ton of money buying several new cam and lifter sets in order to find something to work with the new rule. The current cams that have been in development for years will now be door stops and paper weights. And then there will be more breakage while everyone finds the limits. Some cars will slow down a ton, some not at all.

The high spring pressures are already here as are the cams that work with them. They've been here for a long time, they're not new. We've been dealing with trick lifters for many years, this is not new. We do not need a new lifter rule or a new spring rule.

If you do not want to run ceramic lifters, then buy top quality tool steel lifters and follow the correct procedures. Or, switch to a combination that uses roller lifters with the current rules.

Mark, as far as the crystal ball goes, it is obvious. With roller lifters, the next failure point will be rocker fasteners for those who do get to run shaft rockers. They'll need stud girdles, or shaft rockers. Then what?

But there will always be a fuse, something will always be the next weak link that breaks. It is time to draw the line, and in fact, carve it in stone. The escalation must stop somewhere, or Stock Eliminator engines will eventually be the same as Competition Eliminator engines.

OK, here is the deal. Shubeck / Smith lifters have been exploding for years....This isn't late breaking news. Instead of changing OUR rules , why don't you do what every other racer did......buy a set of tool steel lifters, Trends or Precision ,both are nice alternatives to losing pucks ,blowing up your entire engine and letting EVIL metal run through the oiling system. So sorry if this doesn't fit your agenda !!! GEEZ. ,!!!

Couldn't of said it better myself!

Don't see the problem with keeping flat tappet lifters in stock. The Cup cars have been running them for decades at nine grand or better.

If you have lifters that explode, then don't use them anymore. Seems simple enough to me.

Haven't we changed enough in Stock already? I know it sucks to hurt a motor but almost everyone here has endured that experience. We're racing, **** breaks if we're trying to be the fastest or quickest. Pro Stock, Comp, Superstock and even the .90 classes break break engines. Allowing more and more replacement parts just keeps escalating the class beyond it's original intent and most average racer's budgets. JMT.

Leave stock alone,is fine the way it is.

I will do what the rules allow. This is the first lifter break I have had with a Schubick/ Smith. I broke one when the rod broke in La. years ago. Lost one at Indy when a head of a valve popped off but still qualified. This is the one just failed but I don't know why. Maybe I have been lucky all these years.


I ran these lifters, cam, and valve train all year, and just got off the dyno and it made decent power. News flash peak power is at 6200-6300, and rod and piston weighs 1755 grams each. It's kinda like racing a diesel. I have a nine grand tach and about a third of it is never used.


A 10,000 rpm 396 is Jim Boudreau backup engine, what the #1 engine will turn is still classified information.

Not it is not.
Especially with all these comments.
The Spring Rules needs to be looked at.
If no change fine...
But the current spring rule is breaking too many engines.

Seat Pressure and Open Rate can be regulated.

So why go there, its too late, just like all the changes I listed in stock to the motor already, again to late ! I could go on the changes to the rest of the car ,aluminum radiator three speed trans in place of a two speed not to mention the cost of those trick transmissions, after market brakes, aftermarket seats, etc.. It is obvious the Stock Eliminator cars have one foot in super stock and the on a banana peal now, but with that said does anybody think the lifters if one (desires) to use them are going effect any thing at this point. How many of the items do you already have on your car or how many engine builders use the parts I have listed to racers helping to move stock into super stock. Is anybody ready to remove all the accepted parts that NHRA allows !
