BREAK-IN PROCEEDURE (click here to see how its done)
All engines are pre run for 25 minutes with outer valve springs only,
using a premium petroleum based engine oil containing 8 oz of a quality high-zinc 'break-in' additive.
Inner valve springs are reinstalled.  Engine is run again to adjust valve train and set timing.

Engines are sold 100% complete and assembled, less carb and valve covers.

To make the most complete Pontiac crate engine available, we offer the
following options, all available and installed during in house engine break-in;
*Choice of top brand carburetors*
*Traditional Pontiac pulleys with all related alternator/power steering brackets*
*Blue printed mini starters**Ported Edelbrock cylinder heads*
*High compression engines**Intake manifold porting*
