I don't think there is an electric fan on the market that would fit in the space provided in a jeep that could even come close to cooling your motor. I use a stock 7 blade with a clutch on a 3 row stock radiator and haven't had a problem yet. I think the stock pulls somewhere around 6500 cfm and i have a pusher fan that is good for another 1600 if i need it. I also run a 195 since i have fuel injection. Also why don't you have room what is this motor in?
I was going to take off my stock fan and put in a pusher and puller, I don't like the idea of my fan being that close, I go through too much water and don't want to bend a fan into my radiator. The electric fans should have NO problems colling a 401, I know plenty of folks that do it with their 360's. I will let you know how mine performs with the electric fans.
anyway I run a 4 core with the stock fan w/clutch and have no problem it runs around 190 on the road and 180 and lower on the trail.
If space the issue you could run a fan without the clutch,but do not forget to put a shroud on it you must direct the air through the radiator
Thanks for the replies thus far. Yes the 401 is going into the Willys Wagon engine bay, I've actually shortened the wagoneer frame and am putting the willys on top. The 401 is slighly longer than the old Huricane 6 with all accessories on. In order to get as much room possible I can move the engine 4" back, but was thinking if an electric would work that I could leave the engine where it is and not have to mess with new cross members and mounts.
This engine ran fine in the wagoneer and didn't have overheating problems, but the willys bay is smaller and I'm exploring options.
My old roommate had this same problem. He solved it with a Be Cool radiator, a shroud, and an electric fan in front of the radiator in a CJ-7. He had to grind into the back of the grille to clear the electric motor a bit but it worked and was a very clean install.
I suggest you call Howe Racing Radiator and see what they can do for ya. They use the same cores as Be-cool at less cost and are a top notch product. Mine was a total custom job and fit perfect. Same size as the previous unit and using the same fans a saw a HUGE temp drop.
