I know they are a bit pricey, but they well worth it. Also why install used cams when everything else is new.Honing the block takes out all the inperfections in the cylinder bore, such as scratches. It also cuts new cross hatch marks in the cylinder walls. Boring it out is just that, making the cylinders bigger. If you do that you will need oversized pistons, and rings. If you bore it out it will increase your cibic inches, but it could also make your car run hot if you take out to much from the cylinders. I don't know the limmits on the 4.6, you will need to ask the machine shop. But .030 over is probably max.Make sure you bring the crank to the machine shop with the block so they can check it, and cut it if needed. If they have to cut the crank make sure you get the proper sized main and rod bearings with it.The first engine I did, I was given the improper bearings with the crank and did not check it. After about 100 miles on the car I noticed a slight knock and had to yank the engine and replace the bearings.</blockquote>
