Re: roller rockers
Consider this guys; the ratio on most aftermarkets is stamped on them, and if it doesn't match the specs, it probably won't pass even if the cam passes. And it don't seem so complicated to me; if you got shaft rockers like mopar, don't change the shafts, just the rockers: Studs, keep the configuration, don't machine the head for small shafts etc, And if your unmarked rockers are 1.6 and the spec calls for 1.5, don't be surprised if you need to replace your cam for the 1.5. Basic math (I think). I don't see nothing sinister here. However I'm sure someone will show me the error of my ways; but I'm used to it cause I been married 46 years.

Re: roller rockers
My understanding is that NHRA is building jigs to check ratios.

Somehow I doubt that. They'd need one jig for each engine produced and legal for Stock Eliminator. They'd need at least 7 copies of each jig, one for each division. That's at a bare minimum. An accepted rocker list is much more likely. Especially since a jig that fits one brand of 1.5:1 rocker arm for a small block Chevy may or may not fit another brand. And that is just one engine of dozens.

This will be one of the easier checks for tech to do in teardown. Just check the lift at the retainer, then at the lifter. Then divide the numbers. |

Re: roller rockers
I would have rather had roller lifters to match my cam. Maybe next Christmas.

Re: roller rockers
Darnit Kyle, you know if I had NOS I would run it in Super Gas where the DP's and CJ's should be.

Re: roller rockers
Super Gas? How would you slow them down that much?
