Lifter rule in Stock
Does that mean aftermarket roller lifters are ok as replacements?

Re: Lifter rule in Stock
The rule change effective today takes out wording about aftermarket lifters. I will look again. More later.

Re: Lifter rule in Stock
The words 'oem type' have been eliminated from the description. See 2017 Rule Changes. Anyone know the meaning of this?

Re: Lifter rule in Stock
Does this mean that solid lifters are now legal? In my mind Stock hasn't been using oem type lifters for years. Light weight ceramic lifters don't seem oem type to me.

The only thing that chages is a "Solid" can replace a "Hydraulic" basically nothing changed.
As per NHRA tech Dept today.

Re: Lifter rule in Stock
So throw away all trick hydraulic stuff and go to solid lifter cams. Will make cam checking by NHRA (and racers?) a lot easier, don't have to pull anything apart to replace the lifter for checking. Of course ya gotta buy new stuff.

Re: Lifter rule in Stock
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!

Re: Lifter rule in Stock
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.
