Just a  thought - a "marbles rattling in a can" sound is often pinging. 
If you  have an air leak of any sort, the car would run lean, then run 
warmer, and  then would ping due to the extra heat.

Mike,
 
My experience with A.I.R. (smog pump) Corvairs is the same as Jeff's.   A 
crackling, marbles sound was "normal" under light to moderate acceleration if  I 
had any vacuum leakage from the smog equipment or vacuum hoses.  This was  
with smog heads and raised head smog pistons.
