The various parts and components of your engine have now been cleaned, inspected, and measured where necessary to determine if they remain within factory tolerances or will require machine work to return them to specification. This is the time to assess where your project stands and in what direction you wish to proceed. Is your budget such that the most economical approach is your only option? Or, is this to be a “money is no object, give me nothing but the best” rebuild?

Most projects fall somewhere between a quick clean-up hone of the cylinders plus having the piston skirts knurled to get a few more miles out of them and ordering up an all-outracing buildup. A word of caution here: sometimes the most expensive and exotic approach is not always the best. Instead, I recommend selecting quality parts that compliment one another and your engine (referred to in racing circles as “your combination”) based on the advice of a competent machinist and engine builder.
Some decisions, however, will have already been made for you, particularly in the area of the cylinder block, crankshaft, pistons, and heads. For instance, if your cylinder bores are no longer within tolerance, you will be faced with boring the block, which will in turn require you to purchase oversized (larger-diameter) pistons. During your engine rebuild you will more often than not have the choice to either reuse, refurbish, or replace parts. In the following chapters, you’ll see where I chose to replace original equipment parts with those that feature advances in design and material to gain the best possible results.
