There are aluminum replacement radiators out there that are a direct fit for a lot of vehicle applications. As stated before, the copper-brass radiators are getting hard to find in some parts of the country and if you can find them, they are expensive. The NHRA should mandate that if you go to an aluminum radiator, you have to mount it in the stock mounting location with the stock brackets and hardware. This will prevent issues with trying to undersize/oversize the radiator for weight advantage.

There may not be an aluminum radiator for every application currently however, I would think if the rule change was made by the NHRA the aftermarket would respond with more applications.
