another one for exhaust here, cheap and i love have a good sounding truck (loud lol), free too, just cut off everything right before the muffler!

 

Gear ratio swap!

 

Gosh....

my hand fabbed aluminum billet ac vents
my fabbed aluminum 2-piece padded bed cover
my had fabbed 1960's hemi-style CAI (that actually works)
my hand fabbed rear sway bar (above the frame & axle mount)
my hand fabbed exhaust system 4 foot wye (then I got lazy and went to a muffler shop) where they installed my duel Allied glasspacks/resonators

 

I'd have to say the DP Tuner. Allows the truck to be a mild mannered stock truck when I want and by pressing one little button a few times the throttle gets touchier and the truck just wants to take off like a rocket any time you even think about hitting the pedal.

 

sbc swap and 4x4 conversion on the '51

 

jeez, this is a hard one.
i like exhaust, its not a truck if you cant hear it
i like power,
i like wheels and tires, any thing will look good with the right combo.
i really like having a nice CB in it. the antenna on top gives it that "i know what im doing" look.
when i get around to it im gonna like my AOD swapped in.

heck i like all of my mods.....
