got my 97 truck lowered 4/6 and the stock truck oil pan has smacked the ground a few times and i want to get a shorter one before something bad happens. what are you guys running? i was just gonna order a ls1 pan but it looks like the sump gets moved forward and i'm not 100% sure it wont hit the frame. the hummer pan doesnt look to bad but its only 3/4 inch shorter according to the ls1tech thread.
