30mph of when you are going 5mph is a whole lot different than 30mph off when you are going 100mph. Basically, without a reference point, 30mph is MEANINGLESS.
TH350 and TH350C output shafts are interchangeable back and forth, so all drive gears that fit one will fit the other.
As Crosley has noted, the driven gears depend on the tail housing used. Generally, but not always, the small hole type is used on Chevys while the large hole type is used everywhere else.
