Jeff Dutton ran a 915 box in his 356-\914 special that he drove in the targa Tasmania about ten years ago. I dont know what specs it was built to but it was bolted to a Porsche 6 with about 300 horsesand that was for serious racing. Pretty car too. http://www.sportscarmarket.com/profiles/2001/December/German/index.html
