AlV 69 Dodge GTS project
My factory 2949 068 22" radiator is back from the shop with the New high efficiency core installed. I've kept the original frame and tanks so the numbers are correct.
I couldn't increase to 4 rows because there was no room left in the tank.
So we increased the tube count by decreasing the spacing from 9/16 to 3/8 and increasing the fin count from 8 per inch to 12 per inch.
These changes effectively increase surface area for cooking by roughly 25% so it's like having a 4th row :)
Here is a great primer on High Effeiciency radiator cores
