You might be able to use the V8 radiator with larger hoses if it's configured otherwise like the 6 cyl one. Just use a liner inside the hose at the engine connections (a short piece of smaller hose inside the larger one). It would look very close to stock, and only the most eagle-eyed inspector could tell if you did a good job of finishing the ends of the hose with the liner inside.
