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.
