Unfortunately the 69 factory Hurst AMX has a factor of 7.49# , Just enough to keep it out of AA/S. Unless you can adjust down 1 class with it. .................... Of course you would have to find someone at the New Chrysler Corp. who would push it thru to NHRA, since it was only a 50 unit car! .... I dont know if a car that is an accepted 50 unit combo in Super Stock is automaticaly accepted in Stock. ...... Tom

I believe that if you really look at the specs on that engine(1969 390/340 AMC) , it will pretty much be a no-go for AA/S anyway (at 407 hp).
