WHAT??????
My 82 C10 6.2 sounds like the motor is in the cab with me.....
its got the foil on the floor and firewall,, double tar pads every place and the engine compartment deadening,, rubbers between the fenders and cab and ya still have to have the radio cranked to here it,, forget about having a conversation.......
my 78 K10 short is whisper quiet even with the cooper stt's / headers and magnaflo exhaust.......
