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.

No need for complicated stuff.

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.

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

When it comes to STOCK ELIMINATOR,the saying "Christmas comes sooner than you think" might just be the case!

Just remember, the change to roller lifters will modify the harmonics in your engine due to the knife edged crank which will alter your NOS settings.

A consideration.

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

[KRatcliff]

Super Gas? How would you slow them down that much?

With a keyboard and a mouse, how else!
