Welcome to the Bottom End Section. The Bottom End discusses the short block parts of the engine. This section is divided into the following:
 Block Work -
This section discusses the process of preparing a used engine block. Measuring the block and checking for cylinder wear and bearing alignment,
align honing, unique bearings and seals for the 400 SBC and cleaning the block.
 Crankshaft work -
This section discusses machine shop work on a used crank to bring it up to proper working specs, the unique woodruff key and the harmonic balancer
used by a 400 SBC
 Machine Shop Hell -
Here's the story behind a machine shop and what happens when everything seems to go wrong at once: bad crankshaft, missed
piston pressed in wrist pins and using non 400 SBC rod nuts. The saving grace is a machine shop that stands behind its work regardless if it is
a year later!
 Engine Assembly -
This section discusses assembling the bottom end: camshaft, piston/rod, crankshaft, oil pump, oil pan, timing chain cover, finding TDC and a list of
bolts needed for a SBC.
 Starter Motors -
This page discusses the different styles of start motors used by a SBC and the flywheels and bolt hole patterns.
