Casting Numbers for the Buick Turbo V6

Casting numbers are taken directly from parts believed to be correct. Several castings may be used during a production year or some castings may be used for various years. Use them as a guideline only! Unfortunately, most are well hidden when installed on the engine.  Intake manifolds are the best way to ID an unknown set up.
