Thanks for the link. I just looked at all of those aluminum radiators on eBay, and none....not ONE....had the water inlets and outlets in the right place for a Chevy six cylinder. They're all built for V8 conversions, so that doesn't help much. Trust me, I've spent WAY more than 3 seconds looking for radiator options.
efi-diy, I have an aluminum fan now, but if I need a larger or a bit more exotic fan, they're inexpensive and plentiful. Ditto for high-flow thermostats. There are about 8 or 9 different brands and types available. The two that got the most positive and consistent reviews were the Milodon and FlowKooler thermostats, and they were also pretty inexpensive, so I may order a couple just to have on hand
