slant 6 radiator on a 318

Probably not a good idea particularly using an automatic transmission, it probably won’t provide sufficient cooling at high ambient temperatures, and upper and lower hose connections won’t line up nicely with V8.
I have a beefed up slant connected to a 904 with output similar to a stock 318 cooled with a stock /6 radiator, and when ambient climes into the mid-eighties (we call this hot weather in Maine), the engine tends to runs hot out on the open road at cruise speeds. I now wish I had ordered a HD /6 radiator, or modified V8 radiator to keep up with excess heat generation compared to a stock slant.
I wasn’t thinking like a thermodynamics guy in terms of BTU generation per power output of engine at the time, but just counted the number of spark plugs, and clicked the mouse… if you get my drift. LOL

If the slant had factory air, you should have a full width radiator that cools similar to the stock V-8 one. Later cars had 26"W radiators, which sure helps (you didn't tell us your year). If an early 318 with the cast-iron water pump, the lower hose is on the driver's side so won't work with a slant radiator. The cooling you need depends on where you live and what you do with the car. Many cars overheat climbing out of the LA Basin going 60 mph steadily uphill in 110 F weather. Even a brand new factory design is barely up to that task. Add towing a trailer and smarter to go slow in 2nd gear.
