I was an automotive machinist for 8 years and built quit a few performance and stock engines. Generaly the main caps are cut on the mating faces before boring or honing to make the bore smaller for resizing. On an engine that still has the original caps and not worn badly the only thing needed is honing. If the caps are replaced with aftermarket caps you must align bore before honing due to the additional material left in the new caps. As a general rule align honing is alot faster than boring and usually has a better finish. Align honing may take 30 minutes or so and align boring could take several hours depending on the amount of material to be removed. |
