not all of them,the early ones had drive by cable setups and the body has the same part number as a car throttle body,the only difference i can see is the water fitting on the under side and the pcv hose connection on top.
From a mechanical / driveability angle, absolutely nothing.
Some trucks had the larger throttle cam like most F-Bodies which gives a different pedal feel. Some truck throttle bodies had a small hole drilled in the blade, others have a larger hole and others still have a rubber plug in the hole. I think I've even seen one with no hole, but I can't remember.
I've never had a problem interchanging any of them in a swap.

•There are 2 different mechanical throttle body arms. The photo on the left is the short arm, it can be easily recognized from the round collar. The photo on the right is the long arm, and the collar is straight. You must use either an adjustable throttle cable, or a throttle cable specific to that throttle body for the throttle to open properly.
•There are also 2 basic throttle bodies : car and truck. The difference is the coolant passage for water pump clearance and the breather hose angle (for throttle bracket clearance)
98-99 LS1 Camaro, 99-03 LSx based Truck throttle body. Uses short arm. 00-02 LS1 Camaro throttle body, uses long arm.
