Are new aluminum radiators better?

For what it is worth- a few years ago when I broke a motor mount on my 66 with a slant and the fan rose up and tagged the top tank and cut a hole in it....
Anyhow I tried the 67-76 style radiator from a slant six car and it would not fit. It bolted right in but the offset was too close to the fan blade.all factory car. The top tank on an early abody is huge and overhangs the fan. Keep that in mind when working with the radiator. I ended up after 3 different radiators just re-coreing mine and repairs ($600) and it was perfect. Also added straps to prevent the motor rising up again and tagging the radiator. The rubber sandwich mounts broke from age not horsepower. Sad but true. Love the working car story. We want to hear more about that!
Good luck- Joe
