What is the gas tank capacity of a '70-72 GS?What is the typical gas mileage,(city/highway) of a stock,1970 GS455? Thanks,
My 1970 GS has a 20 gallon tank. I suspect that a "stock" engine would average around 14-15 mpg. My car was getting 12-13 mpg with it's mods. We'll see if that pics up much with the 200-4R trans.
