[in deep 72]

Even if you run electrics, you should have a shroud. I put a new aluminum 3 core radiator in with dual 12" electric fans mounted right to the radiator. I've had an overheating problem ever since (running a strong 468BB). After talking to some big block drag racers they told me to get a shroud. The fans mounted to the radiators will pull air through only where they are located when your not moving, the rest of the radiator will do very little cooling. A shroud will make them pull through the whole radiator. That was my project for the weekend. Making an aluminum shroud and switching to 16" fans.
