New radiator, new heater core and replace all the hoses. While you have
it out replace the front seal in the trans if it's an automatic.
new distributer IF the original shows a lot of wear.
Exhaust manifolds in good shape? Now would be the time to work on them
if the bolts/studs are rotted.
Clean and paint the firewall?
Some places can clean and refurb your radiators cheaper. I dunno with
plastic like we have now, but I would check into it if there is a shop
nearby. I always had them "boil" -clean radiators in the past when changing
out motors few years back, but times have changed so who knows nowdays.
