Valuation of a 78 Row 930

[sundevil64]

I just acquired my first 930 which is a 78 RoW car. It's number 100. It's a coupe w/o a sunroof. It needs some TLC. It has some go fast goodies such as a K27HF turbo, SC cams, GHL headers, either a Garrett or Kokeln I/C, and a lightweight Alum pressure plate. The body is straight. It could use a paint job, but would benefit a lot from a wash and wax. I was going to use this for fun and track, but I also need to insure it. I was thinking in the range of $20k. Does that sound realistic or a little low?

Thank you in advance.
