John,
Thanks, glad you were there. I wasnt sure why the car would have F/S written on the windshield at a SuperStock meet, I didnt know they ran stock class at those.

This raises another question though:
SS/E=8.00-8.49 lb/hp
SS/F=8.50-8.99 lb/hp

So the 429SCJ had to be seriously factored to make it up into these classes. For the 71 Mustang:
3485/435=8.01
3485/411=8.48
So to run in SS/E=8.00. the factored HP had to be between 411-435.

For the 70 Cobra:
3834/450=8.52
3834/427=8.98
So to run in SS/F=8.50, the factored HP had to be between 427-450.

To fit both cars, NHRA must have factored the 429SCJ/375 HP to 427-435, or probably 430 HP. If true, it's no wonder nobody ran these engines much, that is some pretty unfair factoring.

Are you SURE about the SS/E and SS/F markings?

I thought maybe you had the wrong year, but the SS/E and SS/F class breaks didnt change from 1970-1973 or later so that couldnt be it. Maybe they really did factor these things to 430hp. Dont know why.

Thanks again for helping solve this mystery.
