2 - 1''Row Alum rads Any good

There are several types of radiator construction....plate fin, stacked fin, staggered tube and others.

We ran a 427 Ford on the dirt tracks years ago...used a plate fin radiator from a 40's Lincoln V-12. Never got over 180 degrees. Never had to cool it down.

I've had to replace a few radiators in my trucks over the years. A rep from Modine told me when Peterbilt designed the new for 1987 379 conventional they wanted a radiator that would last 1,000,000 miles. They chose a plate fin radiator design.

The one iny 379 lasted almost two million miles until a drink illegal pulled in from of me.

A staggered tube design will generally be the best in an automobile. The tubes get more air flow.

Two tube radiators are ok if sized correctly. Two BIG tubes.

I prefer copper... When push comes to shove aluminum just can't compare. There a zero aluminum radiators in HD trucks and equipment. Well maybe in Volvo's or Freightshakers...those are trucks for people who don't know trucks.

US Radiator carries a nice line of copper radiators.
