I don't know if you've considered used but #304 is back on Cobra Country. It's pretty heavily optioned, including the SS frame:

Scroll down till you see the listing for #304. $95k for a car that would cost about $120k+ to build. With both induction systems, it's a pretty good deal.
Here's the original thread where the original owner sold it a while back:

Offer the guy $90k and see if he bites...
