Front wheel travel; 88-98 C1500 vs. K1500

Hello! I'm interested in buyin' a truck. I don't need 4wd so I thought I might prefer to save myself money and get a C1500. The other day I saw (what appeared to be) a stock C1500 go up on a hydraulic lift for something like an oil change. I saw the rear axle droop at least 6" but the front wheels only travelled maybe 3-4" at the most while the truck was lifted 5 feet off the ground.

My question is this; has anyone noticed what kind of wheel travel a stock K1500 has? I heard that without going to a straight axle it is near impossible to get more wheel travel out of a GM IFS 4wd front suspension. If I can only get a maximum of maybe 4" (or less) of downward travel on a tire (with no weight on it) without going to a straight axle I'll stick with the lamer 2wd truck.

(Ideally I'd like to see the front suspension able to extend down as far as the rear axle does)
