Anybody done an in-car cam swap?

Well I have done it 3 times and plan on doing it again this spring. Its not bad if you have a few days-you think it go faster but for me it seems like it takes me awhile. Cleaning parts and no power tools slows me down. The big problem now is my back-gets stiff from bending over. The timing cover is the worst part for me now. The way I see it is by the time I yank the motor out-the cam would be out or almost-so thats why its in the car for me.
