Would a hood scoop help my problem?

Yes there wired with relays.

My old eng, it took some time to cool down. this eng, i pull in the pits, with fan running, hook up charger, electric fans turn off within minutes. Water pump turns off within 15 minutes.(Note: this is in 75 degree weather.) and this engs has more compression too!

I think what would be best is to kill the fans AND the alt with my full throttle switch. the only thing that worries me is a voltage spike when they both are instantly turned back on. The fan take more power/amps to start the fan then to run it. I need some kind of delay relay that will turn on the fan.....I'm going to have to think about that some more......

When i built this eng i didn't put my LD 340 manifold on because it required one of them bugeye air filters to clear the hood. If i cut a hole in my hood i can use my 14" open air filter that i have on it now.

Thanks for all the thought and opinions so far!!!
