I would go through the 350. If you aren't looking strictly for performance it is more cost effective. You can do a good rebuild with a kit from Nortern Auto Parts...
I doubt you would have to replace the rods so this kit will work for you. They have other more expensive kits so look around on their site.
What I would replace is the TH350 trans. Lose it. Put in a 700R4 rebuilt to Corvette specs and will you see a major increase in mileage, more response off the line and less engine wear at highway speeds. Look here...
Lots of good info. Run through the RPM calculaters to see the benefits of the O.D. swap... Best thing you can do.
