Lifter rule in Stock

[west coast]

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.

My Bad. Solids ok. Rollers no. Sorry for the mistake. Just as a footnote to history; the first time Cliff Sherman (father to famous J. Allen) shimmed a lifter with a transmission spring was just about the time Chris landed on the sunny beaches of Santo Domingo. Footnote to footnote: That is Christopher Columbus when he landed in Santo Domingo in 1492.

NHRA needs a Q and A section on their site to allow questions to be asked related to any rules changes/revisions.

That way everyone gets to see what Tech's response is

[Robert Simpson]

So to review. This revision it to allow aftermarket style solid lifters, for a solid lifter combo only? Or is this to allow solid flat tappet lifters in place of a hyd flat tappet lifter combo? I read the revision and everyone's comments but just want clarification.

I just emailed NHRA Tech to get clarification on the new language. This is the response:

"The intent was/is to allow the use of a solid lifter in place of a hydraulic, you may not replace a flat tappet with a roller.

Thanks

...and there you have it.

It would have been so easy to add the above statement to the rule change!
As written, it creates all kinds of conclusions and assumptions by engine builders and racers

Thank you getting the correct information and posting the email...

Now I can print it off and put it in the racecar glove box with all of the other NHRA explanations....

I'm going to keep my hyd. lifters, solids would be a lot noisier and then I would have to keep them adjusted, and that might..............would cut into my adult beverage time.

Ok, I'm a little slow sometimes, I was about to buy some good hyd lifters, can I instead buy solids now? Or just wait till all those hyd lifters hit the for sale page?
