1976 Chevrolet K20 Custom Deluxe 6.6L pings
Got this problem from another shop, This engine pings uncontrollably, even with timing retarded to 20 degrees total! Customer runs 91 octane fuel, checked emissions under load and it runs within the proper perameters, not too rich and not too lean! rebuilt car...
