i'm thinking about getting an electric fan, or asking for one for christmas[img]/phpBB/images/smiles/icon_spongebob.gif[/img]. in another recent post, n20mike suggested a derale fan for 65-66 mustangs. it has a full shroud and fits perfectly but only flows 1900 cfm. i'm wondering if its better to go with a fan with a full shroud that flows only 1900 cfm or a 16" spal, or similar, with no shroud that flows 2300+ cfm? this is for a '66 mustang, approx. 300 horse 289, stock radiator with a flowkooler water pump. any help is appreciated[img]/phpBB/images/smiles/icon_smile.gif[/img]
