Lifter rule in Stock

[Myron Piatek]

Just my take on it, but since they ramble on about hydraulic lifters, it might appear that hydraulic rollers may be used in place of hydraulic flat tappets, like Jeff originally thought. If solids were allowed, then the words like "plunger", "plugged" & "bottomed" should have been eliminated.


Solids in place of hydraulics would have been cheaper & simpler. But with rollers you have to change the cam and possibly pushrods & springs to accommodate a roller profile & lifters!

[Jeff Teuton]

I agree with all that, but how many of you have ground up a good motor with flat tappet lifters and aftermarket hydraulic rollers would not do that. I don't have any issue with any of this. I have all rollers, but to guys I know and in my past, I have eaten a few good motors.

If I misunderstand this change, sorry! The guys who use solid lifter engines are getting screwed over do to no chance on manipulating the lifters. It's bad enough that .010 in a hydraulic is considered OK by NHRA. The engines HP were based on the lifter working the way the manufacturer designed it, not the way they are now with a built in lash. Might as well let everyone use solid roller cams and get over with it.

Yes Sir ! Get it over with, solid roller cams need to be allowed, Look cars built after 1985 almost all have roller lifters, that's over thirty years ago and the (getting smaller) number of the older cars are almost fifty years old now, at this point with all the rule changes in stock to the valve train what difference will roller lifters really make .

[Alan Roehrich]

Yeah, give everybody solid rollers.

Then next year, give everybody 0.700" lift.







A couple years down the road, wonder why you have a 9" tire Super Stock class, spiraling out of control.

Alan, I was thinking the same thing...stock lift but any duration...and roller rockers....and now solid lifters...and.....

All them "hyd" motors are going up in rpm now!

A couple years down the road? That ship sailed a long time ago.

X2. If you want roller lifters, go buy or build a SS car!

All I saw in the rule revision was an amendment allowing what has been accepted for years. Ceramic based lifters or coated tool steel lifters are not new,as we all know.If your combo came OEM with rollers, use rollers. If it didn't, does this language imply or specify a change over? I didn't read that.Accepted lifters for the last 10-15 years,be they ceramic based or coated steel, were still an OEM configuration. Running even OEM valve trains with lash isn't new either. What does this revision possibly change?

If all cars can have roller lifters then what are the penalties for HP all non roller lifter cars get HP, lets say 40 hp. What are the rollers lifters and cams worth, don't tell me they there are no gains there. I few people cry about there ceramic lifters coming apart now they want roller lifters for free. Nobody forced you to put ceramic lifters in, the rules don't state you have to use ceramic lifters.
