<VV> Engine noise

[FrankCB at aol.com]

Grant,
    If the noise sounds like empty bottles rattling in  the engine 
compartment, it could very well be engine knocking/pinging.   First try disconnecting 
the vacuum advance hose from the distributor and  plugging it.  Does the noise 
get better?  If not, then next try  switching to a higher octane gasoline (as 
high as you can find) and see if that  helps.  If either of these help, then 
recheck and reset the base ignition  timing as well as the centrifugal and 
vacuum advances.
    Let us know what you find.
    Good luck.
    Frank Burkhard

After  driving a 1965 140 PG convertible in the County Fair parade today, I  
noticed a sound that was not there before. While I originally thought the  
car 
was simply ticked from driving over so much horse poop, it appears  more 
serious. 
It is a loud tinny sort of rattle when accelerating. It goes  away when 
leveling off in speed and is not there when the car is in  neutral. So, while 
I 
suspect something transmission related, I thought I  would check with youse 
guys. 
The tranny shifts fine up and down and the  noise is not speed related. The 
car 
was, of course, the crowd favorite and  got more pictures than the beauty  
queens.
Thanks,
Grant
