My personal experience is that if you are restrained in square inches and over heating  is a problem you have to go to more cores. Had problems after my old jeep as in an accident and the repair shop put in a 2 core. I put a  four core in and problem solved. I think its another one of those application specific thing that determine what you have to do.

Don't know so I'm askin, does a custom radiator have to be a rectangle shape?  Can it Not be built with the tanks at an angle to fit that space?  Although 2 standard tanks I'm sure cheaper than some crazy Carl idea!!!

Due to how the end plates are connected to the tubes in the core,it's not really practical to do an odd shaped core. The tanks can be but not the core.

Dunebound,the effeciency of more than 2 cores goes down,way down. Assume,for illustration only,100% effeciency of heat transfer with row 1,row 2 will be in thw range of 80% ,row 3 is around 30% with row 4 doing almost zero to cool.Most all rad mfgs say 3 is the limit . 2 is preferred .At speed,that 4th row can actually block all airflow thru the core. Square inches and airflow are the answer.

Yes it is!

Also make sure your pump will push the coolant through 2 radiators. With all that extra tubing you need to really pay attention to joints and elbows. Stepping up a size or 2 on the tubing is never a bad idea.

Totally agree,especially on the flow issue since turbulence is the 3rd most important aspect of cooling. Unfortunately,after looking and measuring what will actually fit  I will not be gaining any sq inches of core after all and would only be adding ,as you said,extra flow resistance. If I do have any cooling issues though I can add a single row radiator in the drivers and/or passenger side scoop. I'm thinking that would require an aux cooling pump to keep system pressure and flow up as it needs to be.

  Those BIG desert and dune cars have a LOT more room for crap than this small one does.
