I would say that clears up a lot of questions!

Re: Rocker Clarification is up!!!
 

do the roller rockers have to be steel or is aluminum ok?

Re: Rocker Clarification is up!!!
 

I think they still need to add one line -

Aftermarket rocker arms must have same ratio as OEM for engine horsepower claimed

or

OEM or Aftermarket rocker arms with any ratio permitted

I do like the new rule about being able to reinforce an OEM steel rocker arm!

Anybody have a brand name and part number? It would be nice to see what we need to buy.

Those, if they're going to be listed, would be in the "Accepted Products" list.

As of just now, there is no rocker arm category listed.

So if I show up with Harlan Sharp 1.7 roller rockers on my 327 I'm OK? Are they going to check the ratio?

Still a lot of "what if's"!

Rocker Ratio is defined in your Engine Specifications in the guide.

Re: Rocker Clarification is up!!!
 

I spoke to Nhra tech last friday and was told stock ratio, dont know why its not
on the new ammendment. As pointed out earlier it is in the engine blueprints and
probably why nothing has changed ratio wise. I was also told there will not be a accepted
or required list, Any commercially available unit that fits the outlined requirements
will be just fine.
