I got mine from O'Reilly Auto Parts. Get one with a life time warranty. You may find that it will be the new style, that is aluminum core with plastic ends. This is actually a better radiator for it will help cool that 327 a little easier than the original brass one did. Also I prefer to go with the heavy duty one, any thing that will help on them hot days even with the AC on. Check your local auto part stores. The radiator that you mentioned should be good for the 305, 327, and 350. Even if you found one for the 454 engine it would only give it that much more cooling power. The thermostat is what will keep the engine from getting to cold. Keep the proper temp on the thermostat and your car will be in great shape.
