Re: Smokeys power secrets (noskillz)
there has been a debate on rockers some think they are BS others see the
advantage i didn't remember Smokey puting that rpm as a safe limit :skep:
i've turned them to 6-6500 and only broke a few did ware-out guides pretty
fast but i expected it.

Re: Smokeys power secrets (comp)
Why would a stamped rocker wear out a guide faster than a roller rocker?
Are we talking about a pushrod guide plate, or the valve guide?
Arent aluminum roller rockers supposed to have a pretty high failure rate?

Re: Smokeys power secrets (comp)
You have to remember that Smokey wrote his book before the modern roller rockers were improved to the point they have today. Rollers were considered throw away items back then. They are much improved 30 years later and are much more reliable.

Re: Smokeys power secrets (comp)
Smokey only used factory stamped rockers because the rules he raced under required them. Once that requirement was removed, he threw the stamped ones away and went with full roller rockers from the aftermarket.

Re: Smokeys power secrets (comp)
Smokey's 1989 book says stamped up to 5500rpm; few of us street drivers will see this rpm except on the dyno. I think my 'application' is covered. :thumbs:

ad. info::: "When the rockerarm cycle's the roller tip sweeps back-and-forth
across the butt of the valvestem. the contact point must not move closer than
.020-in. to the edge of the stem" :eek: :skep:
