'86 Custom Deluxe - New daily driver.

[WDE86]

Within the coming week(s), I'll be purchasing an 1986 Chevy Custom Deluxe 4x4. It's a 3 speed manual with the granny low. All original except the engine. It came stock with a 305 and the original owner put a 350 in it. The 350 has 57k miles on it while the truck overall has 167k miles (so around 110k on original 305).

It is currently a daily driver from whom I'm buying it from now, but I will be driving it a lot further daily than he has. He's only put around 15-18k miles on it in the 4 years he's been driving it daily.

I am thinking that right out the gate I'll get new belts and hoses run, plugs and plug wires, change the oil, oil filter, air filter, etc. Is there anything else mechanically I can jump on to be proactive on certain wear and tear? This truck will be going from about 10-20 miles of "around town" mileage to 40-50 miles of mostly interstate travel everyday. I'll post pictures when I get a chance. I'm really excited about getting it fixed up.
