This is an original flywheel out of a 1965 Fuel Injected Corvette that has 60k miles and been sitting in a barn since 1971.

The part number #3791021 was used in the high winding FI cars, as well as the Z-28 of 1967-1969, and possibly other high performance small block models.  168 tooth on the gear, weights 30lbs.  Dated I 1 4 (August 1, 1964; car was built September 24- 1964)

It is in very good condition right out of the car.  I would recommend a re-surface to insure a perfect contact surface.  Ring gear is in excellent condition.
