340 has no balls

it should be plenty strong,unless its overcammed,not enough converter,too high rear gear,or ignition timing off.Usually when an engine sparknocks,or pings,the timing is too high.My small blocks seem to really like less timing than other engines,and they pull real strong.My 318 is pretty strong,even with 276 rear gear,and stock lockup converter in a 904 tranny.Whats your cars combination,ie,engine,tranny,rear gear?
