Partly due to nostalgia, and partly due to delusion, we some how thought we could run the original radiator. The radiator shop was slightly less enthusiastic than we were about using the rusted relic to keep the new engine cool. They were even less enthusiastic about putting a core into a radiator that was eroding before our eyes. Thankfully the internet and our good friend Dan were able to help us procure a new radiator post haste. Pat then did some cutting and adjusting to make room in the engine bay. Hello properly cooled V8, goodbye giant puddles of coolant underneath the truck!
