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).

You must use the 45 degree seat angle.

Dwight, I'd think the Crane fully ported heads would be another stumbling block, Altho they are pretty tame compared to what it would be up against. ....Just an outloud daydream. ........Tom
