Re: Max Wedge aluminum rocker arms

[tom hecht <baddd65@xxxxxxxxx>]

i have gold cranes on my solid cam, they have been
running flawlessly for over 6 years now, this engine
sees alot of heavy abuse at the track, but also about
1000 miles a year on the street, i am paranoid enough
to check them often, but they basically don't move.
before this i had harland sharps that worked the same
way in a race/street motor with no problems.

a brother had steel mopar rockers on his street motor,
with solid cam, he was constantly adjusting his,
switched to gold cranes about 2 months ago, so far no
problems.

i run the car at between 3000/3500 rpm on the highway
and shift at 6000 at the track. 

i have heard of problems, but i also know of several
guys running them without problems, these days it
seems like it has been acceptable to have "bad
batches".
don't get me started with edelbrock!!
