strange noise while accelerating

[Matt Bliefernich]

I recently purchased an '86 4kcsq from a guy who took pretty good care of 
it.  I drove it home from Ohio to Minnesota and durig the drive noticed a 
high pitched grinding sound or it could almost be a hissing?  I have not had 
a lot of experience working on my own cars but am slowly learning.  The 
noise is there all the time but gets more audible when above 2k rpm.  It is 
hard to pinpoint where it is coming from ecause it is not real loud and when 
I open the window to hear it better the wind noise drowns it out.  Does not 
make it while idling or when the clutch is depressed or taken out of gear.  
My only thoughts are that I am hearing the lifters which click quietly when 
idling and sound different when accelerating?  Is this possible?  Anybody 
have any ideas?  Any help or thoughts are appreciated.
