While electric fans are effective, they are generally noisy (well, the ones moving a nice amount of air are anyways) and i like the look for a nice big 5-7 blade fan on a well working clutch in a classic car. Also, some of us are still running 6v. so you can count us out of electric fans unless we want to convert that too.

I still think you can cool just about any motor in just about any weather condition without resorting to electric fans, but in a lot of cases, it's just plain easier and simpler to put a NICE set of fans with a good shroud setup in and forget it.

Now, not really Packard related, but in the Pontiac world, if you have the wrong compression heads and the wrong cam and the wrong fuel setup, dual fans and aluminum radiators and rear mounted batteries and shielded solenoids won't save you from overheating and heat soak and hot no-crank over situations. My 428 came to be with all those band aids on and the previous owner said he could never get it to run cool. Not even cold, just cool enough to not boil over and refuse to start.

Head swap and cam swap later with the above changes, and the dual fans and shrouds removed....cool as a cucumber.

Most of us here aren't swapping non matching parts though, and it's just going to come down to trying to make the system as efficient as possible.
