MC, I agree that if you have a bunch of Al parts, it makes sense to use them, I would just use them in an all Al system. Pumps are a non issue since most of them are plastic and don't care, ditto for the res. Al rads are also easy enough to come by, they are used on alot of the newer Al block cars and on motorcycles (though it is hard to get a good used MC rad, they tend to be 'high casualty' items)

I don't consider all Al systems to be at all bad, though they aren't going to do quite as well as a Cu/brass system (all else being equal). It is only the dreaded "mixing of metals" that I think is evil and should be avoided.
