The car is mine -- and while I run NSS and considered using it as a backup car (since changed my mind) in a Championship Series -- I'm assured by Jack McCormick (in a call yesterday) that the car is 100% IHRA legal for SS/SA. Jack has been around racing for a long time and it is doubtful that he and John would have built a car that wasn't legal for the class they were running.
I've been going through the car freshening some things up -- and it was built very well.
