I don't know for sure, but I do not think the Endurance is just a reworked Marathon. For one thing, it has the extra nylon belt running with the steel belts.
The Endurance has a real speed rating. The Marathon never did. I know Goodyear said under certain conditions, you could run the Marathons faster. However, the Endurance tires have the speed rating of the tire molded into the sidewall.
And IIRC, the Endurance only comes in D or E rating. There are no C ratings, at least in 14" or larger.

It makes sense that the Marathon's would have had the same speed ratings, the Endurance are a direct replacement for that tire. I called and tried to get some technical info regarding the differences between the Endurance and Marathon tires last week. Of course the lady on the phone mentioned a stronger sidewall and scuff guard which I can read online. It really sounds like the Endurance is just a rebranded Marathon made in the USA.
