454 TH400 Swap into Impala

[OldMusher]

I have Thrush welded Muffs....Good choice, 'cause they don't do any quieting whatsoever.  Wasn't happy with the short cherry bombs, so I switched to the welded muffs to quiet down.  Yeah....no.  Nice woodpecker though.  Looks like your 454 is really nice!  Should be substantially louder than mine.  Don't have to have a CD player.
