Cylinder Boring: Testing has showed that even small overbore cylinders (+.030") will distort out of round when assembled in an engine.   Because of this, we bore and hone the cylinders in a custom designed and engineered torque fixture which mimics the compression loads which are placed on the cylinders when they are sandwiched between the case and heads.  In this manner, while they are in the fixture, they are bored round and true so you can be assured they will be that way when assembled to the engine.
$160 set of six. [Up to .030" removed from existing bore.  Larger increases to existing bore, please inquire.]

Corvair Extreme Boresm Kit (Corvair Cylinders). 0.125" over bore. 176 cu. in. displacement! Cylinders are bored and honed using a torque plate fixture to guarantee a round cylinder. Complete with forged pistons, wrist pins and moly rings.
