Oh the horror, what happened to my 340...

i didn't hear anything terrible , of course my hearing ain't that good , to me it sounds like my 360/ 426 stroker when i start it up
did not hear the banging or clanking. i know if i just start my car and don't run it on the highway for 2 weeks it will pop and fart until i give it a good run , plugs get fouled
