I have a Blueprint Engines 383 for my 97. I got a Delphi new distributor figuring they were a supplier of good GM parts. In everything I've seen the is a dimple in the distributor gear(present) and a paint blotch to line it up. there is no slot or paint blotch on the fully composite distributor! It also is a "Product of China".
Also the gear does not look like it has any special coating to be compatible with the HR cam.
