Re: Schubeck lifters
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. ,!!!

Re: Schubeck lifters
Forget the spring pressure rule .I do not read any where on my post suggesting that the spring pressure should be changed and this thread is not about valve springs. 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 !

Re: Schubeck lifters
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. |

Re: Schubeck lifters
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.

Re: Schubeck lifters
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. |

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. D |

Every lobe has a limit no matter how much spring you have there is a RPM which it becomes unstable and starts self destructing the valve train. Larry may have just had lifter get fatigued or damaged some how and caused failure. Mike Taylor 3601 |
