All this dual quad talk made me think of a couple of great muscle car Beach Boy songs.
1.) 409... A line in it is " My four speed, dual quad, posi-traction 409."
"She's real fine my 409."
2.) Shutdown... a song of a race between a Stingray and a Super stock Dodge.
" Pedal's to the floor hear the dual quads drink.And now the Four-thirteen's lead is starting to shrink.He's hot with Ram Induction but it's understood. I got a fuel injected engine sitting under my hood.
Shut it off, Shut it off, Buddy now I shut you down."
