I've got a home built sports car with blown LS engine myself. On top of the supercharger, I've also converted it to SOHC. It's not a Cobra but a Ferrari GTO. I've got a build thread on another site:
C5 gto - All MetalShaping
I really like what you're doing with your Cobra, especially the novel engine angle. I also used C5 Corvette suspension, transaxle, etc. on my GTO. Now that I've said this, you can figure out where my user name comes from
Anyway, thumbs up on you work!
