I guess everyone has a radiator story if you have owned a pantera for a long time.

I think I have purchased 5 radiators over the years.  Everytime a vendor had a better one I tried it.  Single pass, double pass, brass, aluminum, 3 row 5 row etc.

I finally had one made localy in brass/copper from the brass cap ends of a vendor one that I think was interesting.

A normal radiator has tubes that are lined up with copper foil folded back and forth between the tubes.  The copper is soldered to the tubes.

The core that we used was totally diferent and was considered commercial grade.
  
Instead of tubes lined up, the tubes are staggered.  The idea is the tubes do more cooling than the copper foil.  Then instead of the foils being folded back and forth it is a strips of  copper the width of the radiaor that goes staight from top to bottom,  The copper strip has holes that I don't think are soldered to the tubes only snug fit.   This is suppose to be like a semi truck radiator and is suppose to let more air through and better cooling with copper/brass.

Mine was unfortunately damaged in shipping and arrived only a couple of days before Concorso Italiano so there was no time to get another one from Merino before the event. Fortunately, Larry Stock (PPC Reno) had a stock style copper-brass radiator in stock for the same price that he dropped off for me the next evening. Stick with the stock-style brass radiator if you enjoy driving your car or drive it on any kind of road trips. Any service station or radiator shop between here and East Jesus, Arkansas can fix it if you develop a leak. The same can't be said for Fluidyne.

Still contemplating whether or not I want to do that since the damn things have such a high failure rate and the fix is to wire them to run whenever the ignition is on.

If anything, it reduces the efficiency of the radiator, but a laydown leaky aluminum radiator does look cool when coupled with twin sucker fans. Flamesuit on, for those who don't think it looks cool  ;^D
