Rocker Arm Ratio
 

Are we allowed a 1.6 rocker where a 1.5 is listed to make our camshaft lift legal? Thanks for your help.

David,

I read the rule book where does it say what rocker ratio?

Re: Rocker Arm Ratio
 

Rocker ratio is in the blueprint specifications. You absolutely cannot have a rocker ratio higher than that specified in the guide for your engine.

Thanks Alan, I had a conversation last evening and the fellow seemed to think the rule had changed.

Get a cam made that meets the lift spec with the stock rockers

PJ, I heard the rocker ratio was dropped too. I called Travis and he said it was still in full effect. He was the one who checked them at the Allstars this year. Lift at valve as well as ratio will be enforced.

If your rocker has no number (ratio) stamped on it, don't worry about it. I was thrown out because mine were stamped 1.65 and the rules said 1.60. The cam checked ok. Without the numbers nobody knows or cares I think.
