2004 Chevrolet Silverado 1500 4dr Extended Cab SS AWD SB (6.0L 8cyl 4A)
I've been a gm buyer for quite a
while,everything from a 70 chevelle ss
to corvettes to a denali. I am very
happy with my new "SS" I have added a
cold air intake reprogramed the
computer added headers and exhaust.
with these mods it dyno's at 405hp and
440torque. I'm thinking of adding a
throttle body next and then working on
the suspension a little.
One of the best things about chevy's
is how easy they are to modify. the
amount of parts and information
