Never heard of a 600. At least not GM.

There's nothing wrong with a TH350. Gas milage won't be as good as having a 700R4 because it won't have an overdrive. You won't notice it that much unless you have rear end gears like 3.45, 3.73, 4.10 etc. Having high gears like 2.77 will still give around 20-25 mpg with a TH350.

The overdrive of a 700R4 just drops the rpm down while crusing down the highway. Lower rpm means less gas is burned resulting in better milage.

Look at the trans pan...a TH350 looks like a square with a corner cut off.
