Dan, very nice car/rust free body to restore!!!!!
Did u get a rear trunk finish panel with the car? If so is it silver with fish emblem, or black with round Formula-S emblem?
There is NO way to tell 100% what the car was without the fender tag or build sheet. Could be a 340 non-S, 340-S, or even a 340 'cuda package!!!!
Standard rear would be 3.23, the 3.55 and 3.91 was an option, but 4.10 never was. A factory 3.91 gear car is very rare and would be more likely on a 4 speed if at all. 3.91 was only available after a certain time?(i have a factory sheet stating this).
looking forward to more on this car/post............

Hey Thanks Dave,
I'd be jumping for joy if I had seen a black formula s trunk panel, but if memory serves (and looking at my old pics), there was no panel. Matter of fact if you see some of the rear photos, the guy delivered it from AZ to VA, so he put red/white reflective tape on the trunk finish panel area.
I did the old mark the driveshaft and tires when I first got it, but I couldn't remember if it was just under 4 revolutions or just over. Based on your excellent info, I'll say maybe it's the 3.91, but will double check it when I can dig it out and look at it and other things people have kindly told me what to look for.
Thanks,
Dan
