I want more horse power, by removing my stock fan in place of a electric fan. My problem is all the E. fans I find cant be used on big blocks. Is thier a fan that can cool my B.B.?
Is a dual truck fan ever used for cars?:confused:
Thanks :D

I see Electric Fans on BB street rods all the time. Get a 16 inch scewed blade that pulls around 3000 cfm and shroud it! That ought to do it!:whacked:
I use an electric fan from a 95 Ford Windstar van on my Chevelle w/ 454. It cools fine, and the shroud fits my large radiator like it was make for it. There are two fans, one 10" and one 13"....you can wire them to come on together, or one at a time depending on temp. But if the only reason you're taking your regular fan off is to free up a few horses, it isnt going to help much....you certainly wont feel it if that's what you're thinking.
Friend of mine has a low 10 sec. Elcamino w/a BBC. He cools his with an electric fan. Has it on a dash switch. He says the electric fan coupled with the electric water pump works great. He says when racing he sometimes has to turn the fan off and on. If he leaves it on he can't get the 454 up to racin' temp.
I had an electric fan on my drag cars, I don't see where the few extra ponies are worth the hassle on a street car. Oh yeah, by the way, how much horse is that 100 amp alternator taking that you have to have to keep the big dual electric fans running??? Just wondering, never have seen any dyno numbers comparing the two, seems like it would be something of a trade off.... ????
Haven't got that far yet but i spoz' I'll be using the electric fans since I'll have a blower belt in the way. :confused:
That's about where I figured the numbers would be. Must be getting old, I still prefer a good flex fan and a properly fit shroud. Room being a concern, seems a pusher fan could be made to be equally efficient for cooling, if place properly like Denny said. Might have to compare the options next time I rent some dyno time..... Thanks for the insight, Denny.
72 Monte Carlo w/ 455 Olds. 4 row copper/brass radiator, 2 E-fans and all the A/C I could ask for in the Florida heat. Never saw 190 with a 180 thermostat. And ran 12.9's in the 1/4.
The only reason I ran an electric fan drag racing was so I could shut it off and get the engine up to temp quicker....would be curious to see dyno numbers on both setups for comparison. Drag strip numbers don't mean much unless you were running back to back runs and could duplicate all the conditions, temperature, track temperature, barometric pressure, humidity, etc, etc....... I guess I've wasted my dyno money on lesser causes, might have to give it a try.
I'm really surprised to see that no one has issues with electric fan setups. I hang around alot on an Astro/Safari site. Alot of the guys have swapped in 350's, most of 'em have had issues of some sort with electric fans keeping up with the load, especially when towing in warm ambient temps. I'm swapping a big block into my Safari and I know I won't have any room for the clutch fan. Got my heart set on a dual 15" electric setup c/w shroud and 2-stage controller, which recieves inputs from temp sensors as well as a/c signal. Supposedly flows 5,000 cfm. Can't remember the brand, but it's a popular name. The model is the Monster?? something or other.

I think you misunderstood what I said, I'm not running a dual fan, I asked if a dual fan COULD be used. I have a clutch fan currently.

Thats what I've also heard that electric fans, at low cfms cant cool big blocks, that are towing or driven hard. I think the genral info I'm getting is that if the cfms are above 3500 it will cool the engine fine, but often the amp draw is higher depending on brand.

I would never recommend electric fans only for towing applications.
I would presume the reason no one has raised the issue here is this is a hot-rod forum, not a towing forum :).
Really?
I have never heard so many negative things about electric fans.
For cruising on the highway I love having the insurance of them.....496 500hp....12.20's with horrible 60' and granny shift, plus this is my daily and she has never seen 200 degrees.
But thats just me
4speedTerror, I was thinking the same thing....I love mine, they work great (even if they are FORD) The CFM issue is a big one, you have to make sure they're big enough...I ran an aluminum radiator in a big block with one 16" electric fan, and it did not cool enough... you need the CFM's to do the job. How do you like the 496?? Im building one right now, the block is being machined as we speak, and the heads are going to the shop later this week for bigger valves.
This is a good thread, now I know what to look for when building my 454. John, how is the block comming along? Did you have to get a new one or resleeve the other one?
Hi Shawn...it's coming along, slowly...the block that he had, previously sleeved, was NG.....scrap.. So I brought him the one from last year that I trashed..He's going to sleeve that one and it will be fine. He cleaned it, mag checked it (no cracks at all) and he's sleeving and boring it now. Should be done next week. I'll email you with more stuff.
Alright sweet, sounds good man! When you email me then remind me to tell you something... heh I will forget within 2 minutes.
Jon the 496 is the best damn motor i have ever had. The thing makes power from off idle and keeps pulling hard all the way to 6200, and she still has more in her...but i am a little nervous about popping it.
Let me know about your build/plan and we will trade notes.....i have learned alot about strokers. Be prepared though when it comes to the valve train, that with a new stroke finding the right valves and pushrods are ganna be a pain. I dealt with Comp and we when through 3 cams before they got it right, 2 sets of pushrods, and 2 sets of rockers. I dont know if the Comp people are beig outsourced to India like everything else but, i found every village idiot that works there.
But after all the BS it is a hard running motor and runs on pump gas all day, cruise to the track and drive her home.
Good Luck with yours.
I have been having second thoughts on making a 496 instead of a 454.... Man o man. :p I thought that if I will be making a 454 instead of a 383 then it will be more money but then again a step up to make a 454 a 496 isn't going to be much more to get much more HP so maybe it's worth it? (besides the gas)
I HAVE 66GTO WITH A 6OO + BIG BLOCK IN IT WITH A FLEX FAN IN IT A STEWART WATER PUMP. IN BRASS 4 CORE IN IT WORKS BUT NOT GREAT .WATER SPEED AND RAD FINS PLAY A PART TO ON HOW TO KEEP COOL . IS LOT AIR MOVEMENT .SO HOT AIR TO GET OUT. BIG TWO ROW WORK BETER WITH MORE FIN PER INCH IHAVE 50 CHEVY WITH 548 BLOW WITH TO TWO SPALS FAN I HAVE DONE MANY THINGS AIR DAMS NOT RUNNING FANS OVER 50 TO 150 TAKING THE HOOD OFF BUT WHAT WORK IS A GOOD WATER PUMP AND WATER SPEED BUT IF I HAD THE ROOM IT WOULD HAVE THE BIGGEST FLEX FAN IN IT .LOOKING FOR MORE HP THERE IS BETER THINGS TO DO .IF THE BELT IS ON THE FAN IS WORKING ..IF YOU WANT ELECTRIC FANS LOOK FOR BIGGEST CFM GET SOME 30AMP+ RELAYS NO FUSE USE BRAKERS WIRE EACH FAN SO ONE TAKES A DUMP YOU CAN GET HOME? HOPE THAT HELPS**)
Pat thanks for that info you have given us. And not being an ass or nothing just trying to show you something, don't use all caps. All caps means your screaming at us. haha
ok i scream lot my cars have 4ich exhaust it drowns out the rices burners who needs stereo wen you have big block.sony has nothing on big block with 4inch exhaust .run rices burners run**) **)
Shawn, I priced everything out, and it wasnt too much more for the 496...Machine work is a wash, you have to get the block bored and all that stuff anyhow...Heads will work with either, assuming they breath fairly well. My only extra expense was the stroker crank, rods and pistons. You can build a stroker with stock length rods and matching pistons, but it's not a good way to do it...puts lots of strain on the cylinder walls. I went with a 6.385 length rod and pistons to match. So, go for it!! You know I won't advise you against it.
Pat, I know what you mean, I have a huge stereo system in my Chevelle, but I hardly ever have it on, I like the sound of the engine better!! (Plus it's hard to hear with the car running!) And as far as the ricers go, my next vanity plate is gonna say ' NO4NJUNK' John
Man, John, you just talked me into it! I went from a 350, to a 383, to a 454 and NOW a 496? I hope you will be paying for my gas!!! haha. By the time you know it I am going to have some 707 (I think that is what it is) like Pro60chevy has.... yeah right. :p
How much more difference in price did you come up with John, any estimated price range? Also I wan't to run on pump gas, at about 93 octane if possible and then go higher when at the track.
Where do you pick up all your parts at too John?
Shawn, do you have to buy a crank, rods, pistons, bearings anyway for your 454? If you do, then upgrading to a 496 will be a few hundred dollars more. I have to buy an entire rotating assy, so Im looking at crank, rods, pistons, and balancing everything...plus all the smaller things...bearings, rings, etc. That part will vary from a low of 897.00 (pretty good, but lower end) up to 2200.00. Im still pricing the pkg, just spoke w/ them again today. I'll probably end up at somewhere around 1400.00 for the rotating assembly. I upgraded several of the parts already, and I might go a little higher, but not much if at all. I get almost my stuff from Competition Products in Wisconsin. Same owner as Howard's Cams that I told you about. I hardly buy anything from Summit or Jegs anymore. Keep in touch. John
John, I wan't to find a bare block if possible. But if I do find a block that has the whole bottem, end etc. I plan to strip everything, bring it to the machine shop, let them do their magic, pick it up and start over. Mostly why I wan't to do that even though it's going to be TONS of money to do is so I can learn and then also so if I wan't high HP I don't wan't anything stock in there to where it may break later down the road, cause more problems, take more time from me to have to tear it all back down and spend even more money. Like I said I plan to do it right the first time that is why I am going to ask as many questions and read as many books and internet sites now and save me the hassel later. I know that always doesn't work out because you will always have problems but that one little problem and save me a whole bunch of others. :D That's the way I look at it at least.
Thanks for the pricing too. Does that shop your talking about have a website? I need to look into the crank, cam and rods you were talking about and I am going to stay away from Eagle now too. I read in a few other sites like Chevelle and somewhere else that I can't remember at the moment and all I heard was bad things about Eagle cranks and the only good things I heard of was when they were in plain street cars and such not drag cars, etc.
I have a 402 in a 50 chevy pickup, no room at all between the pulleys and the radiator.
Where is a place I can look at a good selection of electric fans. My core support is vertically oriented too.
I am using a griffin rad and dual 11" spal fans for my 327/300hp and the fan will only run for 1or 2 min at a time. The only time it ran longer was on a near 100* day going up a mountain to Big Bear Calif. the housing for the fans have a flex type rubber check that will allow the built up pressure at freeway speed to be released on the engine compartment they are pullers and that is just my experience. This is on my 50 F1 pu. They do use a lot of amps something like 14 amps each and put in a 110amp alternator from power master that thing puts out 70 amps at idle and sounds like a gear drive when it kicks in.

For max cooling from an electric fan installation, many fellows are using the Lincoln Mark VIII electric fan. Here are some links explaining the installation:

where can those be purchased?
that one link said Houston Performance but I can't find anything on that place, maybe they don't exist anymore.
I need a pusher fan though, can all fans be reversed?
To make a pusher, just mount it in front of the radiator instead of behind. It won't be as efficient because the unit will restrict some of the airflow through the radiator.
any idea who sells these
Somewhere in those links should be a Ford part #. I'm pretty sure you can still buy them new at the parts counter.
Does anyone know what the CFM on a mark viii fan is. Nobody at auto parts stores can get that info, nor at the Ford dealer.
I don't see it anywhere in the links either.
