as I've mentioned previously, I've been suffering some bad vibrations
from my clutch, its been making unhealthy sounds and smells and my
dyno pulls only got up to 4700rpm due to these vibrations.
well on sunday, i did 5 runs up a Prescott Speed Hillclimb thinking
that if the clutch was going to go soon, it might as well go in
spectacular style. The clutch survived and I had some good runs (will
post videos on youtube at some point), but the point of this diatribe
(and i'm getting to it...) is that on the 130 mile drive back home, I
noticed that sometimes the vibrations disappeared completely until
next time I dropped the clutch. I figured out that if the vibrations
were present, all I had to do was drop the clutch and reengage it 3 or
4 times so get a clean engagement with no vibrations again until next
time it was reengaged when the chance were the vibrations would
return. this strategy worked perfectly for the long stretches of
highway when it was left in 4th gear.
Am I right in assuming that this rules out flywheel imbalance or
anything else and points solely at the clutch? If so is there
anything else that can be deduced? I'm assuming the only solution is
to pull the engine and fit a new clutch?
in which case, are all small block clutches interchangeable? can I
buy the clutch in advance before removing the old one? I believe good
things have been said recently of Centerforce. Any particular model
that is not ridiculously stiff but can handle around 350HP at the
wheels?
