It will also create the exact piston-to-wall clearance necessary. |  Tolerances are checked and...  Tolerances are checked and rechecked while the hone is doing its job. Piston-to-wall clearance is one of the most important tolerances in your whole car. |  Once all the machining is...  Once all the machining is done, Mark throws the block back in the hot tank for one last bath before assembly. |
 Here's the block, ready to...  Here's the block, ready to be assembled. Thanks, Mark! |  Eddie starts the assembly...  Eddie starts the assembly in the same place that every motor build should start, tolerances. First, the main caps are torqued down to the same specs that they will be when they are in use. |  The main diameter is then...  The main diameter is then measured with an inside bore gauge. |
 Then the crank's main journal...  Then the crank's main journal is measured with a micrometer. |  The two numbers are compared,...  The two numbers are compared, and bearing clearances calculated. This process is identical to the one used for connecting rod bearings. |  The next measurement needed...  The next measurement needed is ring gap. Eddie uses the crown of the piston to push the rings into the cylinder evenly. |
 With the ring sitting in the...  With the ring sitting in the cylinder, Meza uses a feeler gauge to measure the ring gap. |  If a ring needs a bit more...  If a ring needs a bit more gap on it, Eddie will use his custom automatic ring file (we're jealous, too). |  Torco assembly lube is generously...  Torco assembly lube is generously slathered over every moving part in the rotating assembly. |
