What Aluminum radiator?
I have Griffin rads in my cuda and 03 Ram with 408/Vortech supercharger.
There has been recent postings in Facebook commenting between Griffin and Champion rads. The Champions are getting a few negative comments. Mostly about welds, made in China and Champion uses 5/8" tubing rather than 1.25" tubing of the Griffin.
I've never ran Champion but can say the Griffins work very well.
