i once had a car that the timing chain was so far off... i had to move all the spark plug wires over one on the distributor then play with the timing ..bingo...hahaha hey it workedROFL

So how did this pinging problem end Zedguy??? Bye the bye. Was the cylinder head shaved? What was the reason for the rebuild anyway? Was it really pinging, because advancing the dizzy timming would only make pinging worse. Not Get Rid Of It! Sounds like a scracthed rocker arm. Or A bad bearing somwhere. :devious:
