26 inch ECP in a 68 Dart

I am probably going to switch my son's car away from a Champion to a Griffin 1.25" tube cross flow rad. They run around $275, not the $620 that the direct fit Griffins cost. So 72Blunblu needs to recognize that there are multiple lines in the Be-Cool and Griffin brands, and IMHO is unfairly biasing the readers against them based solely on the cost of their more expensive product lines. This is not helpful to the general readership who are looking for the best cost and best cooling solutions.

I conservatively compute the cooling capacity to be in the 15-25% range better for the 2x1.25" row crossflows versus the 3x3/4" downflow Champion. We need to get better cooling capacity in the rad due to:
- the smaller early A body engine compartment not being as good for airflow IMHO
- having an AC condensor and external trans cooler up front of the rad.
The 3x3/4" Champion is just not doing it for overall cooling capacity at interstate speed, when moderate HP is being produced.

And FWIW I would pick a 2x 1" row rad over a 3x3/4" row rad for a slight overall cooling capacity advantage. The ECP's and Be-Cool's have that advantage. This does not include the apparent coolant flow limitations that some 3/4" tube cheap rads have been reported to to have. I can't shed any more light on that last issue; I am just relating what I have read on that matter, and have not really examined what is going on there.
