The Ai/ERE-383 mixes a Race ERE-383 with one of the best heads/cam/valve-train packages available for the LT1.  Advanced Induction Cylinder Head Development is considered by many to be one of the top cylinder head porting companies.  Ai puts to good use a large array of state-of-the-art machining technology along with careful component selection to help produce very successful top end packages.  Here is an ERE-383 short block mated to a premium Ai top end.
