0-60 run in 8.1L 03 silverado
This is my dad's 2003 chevy silverado 2500HD quad cab. It's got an 8.1
liter, 496 ci vortec with an allison 5 speed tranny. It's not the fastest
truck out there, but it moves pretty good for it's massive size and weight.

pcm4less custom tune k@n cold air intake, magnaflow true dual Exhaust, chipped. Dyno 485 which is pulling power
for this truck. this truck is not set up to race but i have ran a duramax
diesal and ate him for dinner lol. the whining you hear is not the motor
about to blow up its a tensioner pulley going bad.
