It would be helpful if you gave more info as to why you want an aluminum radiator in the first place, what particular problem, high or low speed cooling problems or both? and also what your current set up is now, rows of radiator, boiled? baffles? mastic fillers? If you want an aluminum radiator just because of the current fad that's fine too just remember they are not all created equal and some do not fit the original shroud or opening very well, Hopefully someone with direct knowledge of a particular brand that fits perfect can chime in.
