You'll probably find someone whose done one on their Buick or Cutlass, which also used the 307 in the early '80's...

I personally don't think there would be any benefit gained from having an electric fan. The engine driven fan freewheels most of the time, so there isn't that much power or economy loss. The electric fans are expensive to buy, and even though they free up the crankshaft, they cause such a power drain on the charging system, that any power an economy gained is lost through the alternator.

Yeah but they have to be quieter than that noisy mechanical fan on my old 350 chevy truck motor

I did it to my wagon. I used fans out of a Regal GS 3800 s/c. And used basic 30amp relays. I do need to hook up a controller.

Some use the fans out of a 3.8 ford taurus becuase they are two speed.

Here is a Mark VIII fan being used.

No gain for real, it just cleans up the front of the motor
