Rebuilding Numbers Matching 383

Drove my newly rebuilt 383 today. When I tried to set my car for total advance, did not line up with marks on my balancer. hmmm... Set total timing by ear and took it for a spin.
Did not run great.
Started trouble shooting. Here is what I found. My free distributor from a 400 has no mechanical advance. Oops, didn't think of that. On the prowl for a distributor.

Who needs 32-34 degrees of advance anyhow?
