i have a 4.3 vortex v6 in a single cab with 4.11 gears. it cruises comfortably at 50 but am really looking for 70mph cruising at about 1,000-1,200 rpm. What gear ratio should i put? and any tips for doing the swap?

Nice looking truck.  Going back to 1980s vintage gearing, you'll want a 2.29 ring and pinion set to cruise at 1193 rpms in 4th gear (mathematically).  Or get a Gear Vendors Overdrive to put on the end of your transmission or transfer case.  Assuming they are still around!
