roller rockers

We're currently working with Harland Sharp with the Gen III Hemi roller rockers. With the new NHRA approved 1.65 RR and our NHRA approved rocker ties, should make a for good combo, course Harland Sharp will have to submit the package to NHRA for approval.

NHRA has not issued any rule clarification, as of today. I would not suggest to anyone that they buy anything until NHRA produces a clearly written rule. One thing every racer should learn about NHRA rules: Get it in writing from Glendora if you want to be sure it is legal.

Amen!!!!!!!!!!!!

I thought the rule was and is “Any rocker arm permitted.” ?

Even then it could be different the next time you go through tech.

Until it is fully clarified and there is some sort of a list I would wait to make a purchase. The rule as it is, is too vague. Jim

I talked to Tim Cole yesterday and the understanding is stock configeration, stock ratio. there will no shaft style rockers for BB/SB. Ford, Chyrsler, AMC if they came with shfts you can run the shaft system.

This is pretty much what I posted it would be a while ago, however, IT"S NOT IN WRITING YET! which makes it open to each individual tech guy's interpretation. Just a warning. You can bet there will be an accepted list. It's not like roller rockers are going to give you 20 horsepower so don't be to quick to run out and buy them. Be safe rather than sorry (and poorer). Jim

Their must be a goal when NHRA change the rules,,, and i think that the goal must be like this:
Better easier and less money for the racer.
Easier for the tech to do inspections (= less money for NHRA)

This goals should alwayes be their , and be the main thing when the change a rule. And in that case the could always explain to us race WHY.

So is this goal heir with the rocker arms rule ?

The racers : Easier to find ? Less Money ? Better stronger ?

The tech : Check ONLEY valve lift as per the rule book with Zero lash.,, thats it = Easier.
Stock style rockers ,, Studs for the studs like Chevy and shaft for the shaft , like Mopar, use what ever ration we whant, but it must be Stock valvelift.

So for fun,,, look at this rocker arms rule from this GOALS ,,, and see what we came up to.
In my world then i think this is a GOOD rule change !!
