You will need a few special tools when it comes time to build or reassemble the engine. A good torque wrench, Plastigauge [http://www.plastigauge.co.uk/], and a cam bearing installing tool (unless machine shop installs cam bearings). Also you may need a ridge reamer, a ring groove cleaner, a ring expander, a ring trimmer, a ring compressor, and a good cylinder hone. | You will need a few special tools when it comes time to build or reassemble the engine.

If you're starting a "project" or work on cars often it would be wise to spend the extra money on higher quality tools. Cornwell, SK, Starrett, Craftsman, MAC and Snap-On are commonly known to be the "best tools". Snap-On is a little better quality, but cost considerably more and can sometimes be a pain in the butt to exchange your broken tool since you would have to chase down one of their trucks. Craftsman is a good brand of tool too and can be bought at almost any Sears department store.

Look on the package when you buy handtools, all those I've seen during the last 20 years have had a Lifetime warranty on them, even the cheapest ones. Both of these brand tools come with a lifetime warranty which comes in really handy, especially when you're removing a bolt and the tool breaks. |

| + | Eventually it will come time to install your camshaft as well. If you are planning on doing this yourself, you will need a degreeing wheel for sure! You can buy these alone, or in comprehensive kits from somewhere like JEGS, or Summit Racing Equipment, maybe even the local shop. They go for around $200. Just the wheels themselves can be purchased for as low as $10.00. You will also need a dial indicator as well as a magnetic stand for it. These can also be purchased at Jegs, Summit or even your local Harbor Freight store. | ||
The larger (diameter) the degree wheel the easier it is to be accurate. | The larger (diameter) the degree wheel the easier it is to be accurate. | ||

If the tool is intended for infrequent to frequent hobby use, the purchase of cheaper brands of tools such as Craftsman may be appropriate. If however the tool is intended for daily use in harsh conditions, especially in the context of automotive repair, an investment in higher quality tools produced by companies such as Matco, Snap On, Mac and Cornwell should be considered. |

If you decide you need some specialized tools that you really don't want to invest money into right now, ask around in your circle of friends to find out if any of them have the tool(s) and will loan to you for the task at hand.
