Unless ski-me has upgraded his, he's running 35's on the stock 208. That's what's in my 85 behind the 6.2/TH400, I'm running 2.5" lift and 33's. You'll be fine. I don't think any one year is stronger than the other. Side benefit, you'll be able to run a shifter and components from an 80's truck, should be easy to find and cheap.
