Afternoon Walt. 94K on a 300 six is not much depending on the maintenance he's done. Not much different checking things. Check the radiator fluid, check the oil and trans oil for burnt smell, color, etc.
The 300 would be a great engine/trans combo for your 62! Pull the smog crap off. Install a Offie 4 bbl manifold, 350 Holly, and a set of headers, amd BINGO! Plenty of pull power and 20+mpg!
