  • @350AmericanMuscle 454 is the 7.4

  • Move the camera away from the tailpipe. Cameras never do exhaust justice.

  • Its a 7.4L? I thought the 454s had the 8.0L or 8.1L?

  • Dude that 454 sounds SICK.

    Followed the link form Truck Forum,

    I think I have a video of my truck's exhaust...I'm not sure

    But seriously, awesome, awesome sound.
