I don't want to completely hijack this thread which is for Ford 460s with fairly high C.R., but what about a mild 350 SBC with 9:1 C.R.? Everyone tells me to use an electric fan, particularly at idle, but what about a flexfan? It's either/or since the electric fan does not leave room for a flex fan. What about a flex fan with a shroud for a mild 350 and a '29 replica "Cobra" fan? Can I use a flex fan with a small electric fan mounted high up on the radiator or is there just no room?
