I like the electric fan idea. i have a 261 in a 37 sedan. With no hood insulation and not such great firewall insulation the noise form the fan was so loud i couldn't hear myself think. I went to a bone yard and for about $15 got the biggest fan that would fit in front of the radiator. I tapped into the thermostat housing with a $8 fan switch from the auto parts store and a relay to handle the 15-20 amps. Works great and the fan almost never comes on. You got to have an alternator cause the generator won't put out enough amps. Good Luck Gael
