Corvair 3.3L Jump Start Kit


The Corvair 3.3L Now Available.

The Corvair 3.3L is a stroked version of the proven Corvair conversion.  The 3.3L has been dynomometer tested and output results are 119HP @ 2800 RPM and 125 HP @ 3300 RPM.

The crankshaft is machined, in the US, from US 4130 Timken Steel.  The pistons are our custom design made by the same manufacturer we have been using for years for the 3.0L and 2775 pistons.  The connecting rods are a custom setup, and the case and cam are modified for proper clearance.

The heart of this engine is the new, billet, made in America crankshaft.  A standard Corvair has a 3.437″ bore and a 2.940″ stroke, yielding a 2.7 Liter displacement.  Increasing the bore to 3.620″ with larger pistons and cylinders increases the displacement to 3.0 Liters.  When that is combined with increasing the stroke by .312″ with a new crankshaft, the displacement becomes 3.3 Liters.  Externally, the engine remains the same size as all the Corvairs, but it is actually substantially lighter because the new crankshaft is lighter than the original GM crank, as are the new cylinders.

The Corvair 3.3L Jump Start kit is a rotating assembly and includes all of the components listed below.  Included is the bottom end assembled –  from the front hub to the harmonic balancer.

See the list below for what is included.

Crating fee and freight delivery charged at delivery.
