Electric or Clutch Fan?

[cr_bobcat]

Anybody have any recommendations? There doesn't seem to be a whole heck of a lot of clearance so I'm not sure if anything will even fit.

8) there are ways to gain clearance, moving the radiator mounts towards the back of the radiator thus moving the radiator forward gaining clearance. or modifying the core support also to move the radiator forward to gain clearance. dump the fan clutch and use an electric fan or two. for instance two ten inch electric fans i believe will fit on the stock radiator core, allowing for an area between the fans to allow for water pump snout clearance. you can also use a remote mount electric water pump to shorten up the engine and gain a lot of clearance. i also saw an article once about using an engine driven remote water pump to gain clearance, essentially taking it off the front of the engine and moving it to the side of the engine. it was done on a small block ford in a tight engine compartment, but i cant for the life of me remember where i saw the article. i think it was an old petersen publishing book on street rods. that was back in the early 80s when i saw it though.

Because our Aussie X-flows and 2V 250's and US log heads run the same thermostat neck, you just need to copy what Our Aussie Six cylinder Cortina and Falcon guys do. They are always having the same problems as early Round body Falcon owners when a 250 six is put in.

See and do a search on balldrick's 1960 XK Falcon. He runs a Davis Craig electric fan.

Each show easily made Davis Craig/EWP electric water pumps which work really well when the instructions are followed.

I think I saw that article too were you mounted a water pump on the side of the SBF engine to get room in a tight Model T, I believe that it was an old Chexy six pump that they used. They have also shortened up the stock water pumps in the past too.

that sounds right bubba.

I have been interested in a thermostatic fan I think it is called. When it senses heat the fan blade will start to turn so it has a clutch in it. On some vehicles like my bronco it looks like I can move the radiator a little like rbohm mentioned. At a car auction I went to I noticed some of the vehicles have a low profile electric fan like the Ford Contour and that would be good choice at least for me. My Bronco runs cool and it is driven in northern NV mostly.

Thanks for the tips. That Davies Craig unit seems pretty sweet. I'm thinking the switch will be further down the build plan till a slightly more economical solution exists. I think that I can get a better bang for my buck in other areas (hp gain / cost) through some other options first. I'm a real nerd when it comes to crunching numbers so I think it's time to start updating my build spreadsheet to compute a $/hp-gained line and see how that rolls up. Granted, this is a "the car is only down for a weekend" kind of fix too since I should be able to fab everything up ahead of time.

I love North American engineering. Do what I do. You can use an SUV Jeep 4.0 or F150 4.9 Big Six accessory drive

The three step plan is to fix

1.the waterspace limitations by EWP pump
2.the wind rush requirements by thermo fans
3. the space limitations of the accessory driver by a proper, cheap serpentine drive.

I'm sure Ford would have done it the way the 4.9 was if the 3.3 and 4.1 had made it past 1983 and 1981.

Even the related front drive HSC 2.3 and 2.5 system can work if you do a further step and remove the distributor as well as the water pump.

Realize the the US 4.9 EFI accessory positions are best.

Even if you have an old 250/4.1, (which from 1975 to 1981 had started changing the Air pump and air conditioning units to the right hand side) or 200/3.3, the 4.9 F150 accessory drive positions still suits any 200 or 250 best. It's a landmark of friendly simplicity, its thin, and it allows you to run twin Fox Modular Mustang style thermo fans so you can get the required wind rush.

You can keep the alternator in the stock late 200/3.3 1978-1983 Fox Ford positions, with the power steering on the lower left, but use the F150 4.9 a/c unit or idler as a tensioner, and the and air conditioning bottom left and air pump on the right.The US 250 used to high mount the air pump on the right. If the air pump goes right, it makes things easier.

Grab the F150 EFI 300 Big Six 4.9 accessory drive, and make it fit the 200 or 250.

They got it all sorted. Its the best engineered piece around. Ford got it rolled out in late 1978 for the 79 Mustang 302, and it never looked back.

Any one can make it work, and its fun

You don't even need a reverse water pump with a Davis Craig electric pump.
