curious on the rocker deal.(i don't have a car or engines involved, plus i sell this stuff) I haven't seen the rule that's why i'm asking. you can't run a steel/billet rocker? if so, why not? they last longer[although a little heaver] than the alum. after numerous heat cycling. this would save the racer $$$$$ in the long run. also not knowing the rule are these stud mount only or are shaft style rockers legal?[also intial inve$tment more but also last longer and takes a TON of strain of the entire valvetrain] thanks db

Don't shoot the messenger, I'm just telling you where it is.

Yet another thing for car owners to disagree on! If no one has a rule book how does the track inforce these rules in tech?? Just a question not trying to shoot the messenger!

Print them!

dynamitedave · 08-23-2012, 09:48 AM

Seems to me it has always been that when you buy your number you got a rule book!!!

the crates need a weight break for the shorter events,seems like they only
shine when there is a 100 lapper,

will this help the crate motor compete? it would be nice to help them out. get another option that will compete vs the 30k motor.

There are a lot of Late models in Colorado with and without 30K Motors just sitting.

Wonder what an Owner, or a race Team would think if there was a Competitive Option A: REALLY allowing 604 Crate motors to be Competitive at CNS.

Just wondering WHO it would it really Hurt? Not! Local Fans-Owners-Race Teams or Drivers, CNS Just! Get UR Done.
