Anyway to tell gear ratios in 1978 ford f 250
I am looking at a 1978 f 250 ford pickup, It has a 351m 4 speed 205 combo. My question is is there a easy way to tell what gears this truck would have? There are all the trim tags on the truck. I know who bought the truck new and it is unmolested . He doesnt know what gears it has. Also what type of 4 speed eould this have? sm 465?
