Is there one? I haven’t seen one. There’s a lot of engine fans out there and not all are automotive related. I’ve got a 34 ford here with a SBC and if I could get the fan blade an inch closer to the engine it would save a lot of grief. There’s plenty of room on that side of the fan lol ! He’s got a BS flex fan on it now.
Most "flex fans" are offset completely towards the engine, but many also have thick blades, so you need to space them out to clear the lower pulley. Without knowing more details of the situation, it's hard to make a good suggestion. Maybe you could post a sketch showing a dimensioned side view of the setup, including water pump hub, lower pulley, and radiator.
What Jim said. Stock OEM fan's blades are about 1" closer to rad than a flex. I know, I needed that extra inch so I had to bow down and go flex over stock. But then there are flex's that go forward as well.
Might want to check industrial equipment fans. some come as an assembly Center and blades individual and you can set the pitch of the blade in the center section or buy a certain pitch blade jaguar v12’s or inline 6’s from the 80’s had a very narrow clutch fan..... maybe? The pics are gehl skidteer and hengcha forklift fans so you get an idea of what I’m talking about
Are you using a spacer between the waterpump and the fan ? They come in various lengths. What pump are you using ? Long or short ?
I think that's not a flex fan, it's just a 6 blade OEM type fan. These were used on AC equipped cars in the 60s-70s, although clutch fans were more common.
Ummmm huh,,, It’s hard to see in there and it’s a process to get the hood open and the side panels off but here we go. fan buried in the shroud. something looks a little funny The fan is backwards
yay, we can see what you're working on now! but still can't tell for sure what will fit. It looks like if you put the fan on the right way, it might work, or it might hit the lower pulley, so you might need either a fan spacer, or a single groove lower pulley (but the car might or might not be getting AC, so we don't know if that's a reasonable solution). If you get to the point that you can actually draw, with dimensions, what you have to have, then we can look at some fans and see what's available.
The fan needs to be centered in the shroud opening. It might be better to not have a shroud and have the fan approximately 1/2-3/4” from the radiator core. Many cars never had shrouds and never had a cooling problem because the fan was correct to the radiator. I have run the 5 and 6 blade steel non flex fan and did not have cooling problems because of its location. They need to move air by pulling the air thru. If you get the fan close to the core, many times just a ring of metal which centers in the fan blade will help a lot. Good luck..
Now the fan is on correctly. I’ll be refitting the shroud and see how it lands. Take it from there and see.
I have this fan on wife's 55--17" it has a 3 groove pulley on crank and two on water pump-clears all by about 3/8' behind fan--it is 3/4" back from water pump face and 1 1/4" out-this is a spare that is on the wall
When I was putting my 283 into the 33 pheaton I shimmed the radiator forward a bit. It only moved it about a 1/2 inch but thats a bunch when trying to fit the motor with out cutting the firewall. I look forward to seeing a fan with a back space. I may have to look into making one
I’ve not tried to push the pump flange that far, but cutting the back groove off of a 2 groove pulley might give room
You can tell by the witness ring that the fan was on the right way before and maybe a test fit that way. Might be kinda stupid but I've seen people bend the stock blades back towards the engine to get some more room or push the water pump shaft in more IF you can. ****never mind I type to slow. Another stupid question is does it need the shroud?.
@31Vicky with a hemi , how thick is the billet aluminum pulley where it bolts to the water pump? I bet it's ~3/8" thick. A stamped steel pulley is less than 1/8" thick at the flange; which would move the fan back ~1/4" toward your 1" goal.
They make them where they are towards the rear and have them on the roadster and cabriolet. I usually find them at the swaps and buy them . Even with the flat fan not much space and cutting down the waterpump flange will give you more room but will have to make a new tradition aluminum pulley
Some one on here said he had used a Ford upper pulley and then pressed the water flange on further till the pulley grooves lined up to gain room in front of the fan. I don't know any other details. Gary
