Car has been sitting for 10 years

I bought my 65 "S" in 1996 IIRC, and it had '76 tags on it. The guy said he hauled it out the back of a warehouse and dug up the title to set it out in front of his muffler shop to sell it. I bought it, put 4 gallons in the tank and brought a battery and drove it 20 miles on the freeway back to my house on 5 of the 8 cylinders. Brakes worked, motor didnt get hot...everything worked! Put 8 new plugs in and 2 sets of points and that thing ran like a top. Changed the tar that was in there after idling it with a can of motor flush in it and chunks were glopping out the pan hole. That carter carb was fine after 20 years of sitting but I think the leather pump shot was a little weak. Replaced that, tested OK. Even had the bias ply tires still on it. Smooth ride, but the grooves on the freeway made it float. 25 years later I still got it.
