You could still have the 389.  In 1964 was the 1st year the starter is attached to the block instead of the trans, which would be the 2 speed powerglide. Still very sought after trans for drag racing.

Are you wondering if it a 421 block? - I believe that they were available in 63 and if you have a numbers matching block you have a treasure.  Someone our there should be able to help you with this - you can probably get the serial # on line.  Sorry, but I don't know enough about the HI PO Pontiacs of the 60's except they were great cars.  My Dad had a 63 & a 64 Catalina, both were 2 dr hard tops - I loved them both.

You need ti find the block casting number. Early Pontiacs are on the passenger side. Mid-60s is near the distributor. Later blocks had the displacement stamped on the side. I suspect you don't have an uber-valueable 421 Super Duty, but I included it in the list anyway.
