Chad's truck has been running a little warmer than we like, so we worked today installing high-output dual electric fans with shroud from DeRale Performance.
We purchased the DeRale 16927 Kit from Summit and the construction quality is really nice. The dual 13" fans flow a combined 4,000 CFM which should be plenty for the Big Block. This kit with shroud measures 18" H x 26" W and is 3.550" thick which fits the aluminum radiator perfectly. The fans feature 7 blades with maximum 1,680 fan RPM. Amp Draw is 49.60 amps for both fans.
Dual relay harnesses are included as well as an extra wire for air conditioning over ride.
We had to make a few minor modifications in order to use the factory 4-core radiator hold downs, but I think it turned out pretty nice. Next step is to wire in the relays, fill with fresh antifreeze, a bottle of Redline Water Wetter and pressurize the system. That will have to wait until Monday... it's two hot in the garage for us today.
