You can do it in the car - it's not so bad. You need to remove the front bumper, and the valance. Pull the head, get all the lifters out, pull the radiator & fan, remove the crank blancer, timing cover, chain, distributor, fuel pump. Get a 4" long 3/8" - 16 bolt and thread it into the front of the camshaft. This will help you guide the old cam out and the new one in without knicking a cam bearing.
