Alex - that's the Champion radiator I used. CC1643

I've been very happy with it - but one word of caution -

The inlet and outlet diameters are the reverse of the 6.1 G3 Hemi inlet outlet. (Not sure about the 5.7)

So you end up with 1.75 going to 1.5, and 1.5 going to 1.75

I ended up using two universal Gates reduction hoses 1.75 - 1.5 and another reversed the other way.
