Word of warning, we bought an Ebay unbranded chinese electric fan to supplement the stock fan on our mild small block a body build, just in case we needed it. Never had to use it. During a burn out, the stock fan pulled enough air to exceed the electric fans safe working RPM and it promptly exploded taking out the radiator and part of the grill. Messy  Another point of note is we noticed the car would pick up on et and mph if the fan belt slipped those stock 8 bladers must take some power to turn at high (ish) rpm.
