Camshaft Install Questions

[75sierraclassic]

Well I found out this weekend that my camshaft is going out in the truck. Its a comp cams extreme energy 262 with only about 35,000 miles on it. I measured the lift on the #1 exhaust valve and only saw .120" lift when it should be around .460". I'm a little ticked that it only lasted that long. Have any of you had problems with these cams?
My main question is, how much work is it to install. In order to have enough room in front of the engine to put a cam in while the motor is still in the truck I know you at least have to pull the radiator, but do you have to take of the tranny cooler, condensor, or core support? How much of the front do you have to take off to make room?
I don't have a garage and would have to do it in my apartment parking lot, so I am contemplating if it is even possible. Anyone in the Kansas City area want to take on a weekend project? J/K. I appreciate the input.
