ppl misunderstand the C model trannies all the time
it is not overdrive, overdrive auto trannies were the 700r4/4L60E/4L80E and 2004r and thats it
look for the wiring plug on driver side of tranny halfway back or so, almost next to the shift shaft, if it has none then its not a C model 350, the solenoid for lockup like to stick and not unlock and that causes dying at idle problems, i prefer non lockup models, they only made them for a few years in the early 80s and then did away with them after that
