I was wondering what size throttle body comes in a 05' 4.8 silverado? Also would it help, performance wise, to put an 80mm throttle body on?

Unless you get the 80mm cheap like I did, skip it.

SUCKS and the install doesn't work -Had to buy my own mounting rachet screws - But that is soo true about aftermarket shit.
