There's 2 issues when considering an electric fan.
1. space available. If you'll look at Solracmopar's setup you'll see he barely had room to squeeze the clutch fan in. Most good high perf. electric fans are on the order of 4+ inches thick. On my Cuda I only had 2-3/4" between the water pump and radiator. Could only find a couple lower perf. fans that would fit and I tried the best one I could find and it didn't cool as well as a clutch fan with a shroud.
2. Make sure your electrical system is up to snuff when you install an electric fan or you'll have at least a melted wiring harness, at worse a fire. The fan I tried on my car only pulled 14 amps yet that was enough to melt the factory connector where the fusible link connects. The wiring harness was almost new too, not an old piece of junk. The factory harnesses that directs alternator charging power through the bulkhead to the ammeter then back through the bulkhead to the fusible link then to the battery is a weak system. Too many connections with light duty parts but when these cars were new they didn't have much current draw on them so it was sufficient. I do agree that it looked much better with an electric fan setup and if it would have cooled as well I would have upgraded the wiring like the mod on
