Re: 1983 chevy k20 question
Should be an 85. I'd stay away from 700r4s

The 700r4 isn't bad if you baby it or have it beefed up.

Re: 1983 chevy k20 question
The 700R4 isn't any worse than the TH350. They aren't a workhorse like the TH400 & 4L80 but they will get the job done if you keep the temps down.
100mph stopped around the late 70's. The 1980's speedo and tach fonts are a little big and chubby compared to the '70s fonts and they used eggshell & brown/tan colors instead of white & blue.

Re: 1983 chevy k20 question
You could get a 700R4 in anything below 8500 GVW, 8600 GVW & up got the TH400.
