I'm inevitably going to go with an aluminum radiator, and since I've gone serpentine, it looks like an eFan setup is going to be part of the package. Just curious about you guys running big blocks, eFans, aluminum radiators... what's working for you? Also might bring serpentine setups into the picture as they _might_ block some air from moving around the motor.
I'm thinking about using a ColdCase or other 2-tube radiator, but until it's mounted on the core support, I'm not sure about whether a single fan system will fit ok, or whether it has the CFM to cool my 461. I will note that with the 4-core COPO-style curved neck radiator and a no-clutch 7-blade fan, I had no cooling issues in normal driving in any hot weather.
Things to consider; Vintage Air, possibly going EFI down the road.
Are most DeRale, Flex-A-Lite, Spal and other name brand fans multi-speed? I did read in another thread that in a dual-fan setup you don't want one fan working and the other possibly freewheeling in reverse, it that true?
