I posted last week about putting a 12 or 24 valve cummins into my GM. I am planning on swapping over the whole drive train from a donor Dodge to the GM. My question is for those of you who have done the cummins swap into a GM what intercooler did you use? I have both the Dodge Cummins intercooler and a brand new Duramax intercooler? By looking at them, both I will have to modify the rad support but does anyone know flow #'s or which one is best? the Dodge one does look to have larger openings but both neck down to what looks to be about the same size. The GM intercooler is a closser match to my 88-98 huge 4 core rad that I bought new 6 months ago and would like to keep and use.
Does anyone have any advice or knowlege on which one to use???
