An aluminum radiator can be a great addition to your build; however those advantages are along the lines ascetic - in most cases - rather than functional.

Replacing a 10, 20 or 40 year old radiator; copper, aluminum, plastic or whatever … that was marginal in the 60's running in front of a 170, 200 or 225 (gross, not net) horsepower engine is a good thing for almost any reason you can think of. The point you really need to have clear in your mind is what you are trying to do.

I have and continue to say that a copper radiator is at least as good as a copper - if not better. I will agree that in aluminum is lighter, shinier and gives you a little more "street credibility". It makes great "frosting" on a nearly completed build, but in my honest opinion, is not the best or only solution for every over-heating problem.

I guess what I’m saying is best illustrated by my personal decision. I will change over to an aluminum radiator eventually, but its not because the copper radiator is bad. I’ll make the change because I have the spare money, because it looks good and because it’ll add a little to the “bling” factor.

Maybe I have it totally wrong, maybe once I make the change-over I’ll be another rabid convert to the benefits of aluminum radiators – but so far, I have just not seen the benefits that make me want to rush that decision.

By the way – all of the contributions have been great. You guys have given a lot of information on what fits and how to make it work in Mustangs. Maybe my reluctance is based on my non-Mustang addiction?
