i have a th 350 that i got from a guy on here in southend but
i can find this info on the side that says yoc 03n
now is it possible that someone has changed the gear ratios in side
i have a 55 chevy step side that at 50 mph it is doing 3.250 rpm
my rear tyres are 235/75-15
rear axle ratio is 3.73:1
engine is a 5.0l v8 .
