New SHORT muscle car fan clutch!!

-
some of our members actually had a hand in the R&D of that one, let me see if i can find the thread on that

[2 minutes of searching] Short Shaft Fan Clutch [/2 minutes of searching]
 
Yes I remember posting in that thread quite a bit. A somewhat longer clutch I use in my demon 340 is one out of a 78 or so Pontiac sun fire with a 350.
 
How much do they cost? Where do you get them?

We've got less than 1/4" to our radiator from our clutch fan....
 
I know two different resto shops I told today and both are ordering on Tuesday !
 
Does the heavy duty one still require the centering bushing that the Shaguar one has, or is its hub made to fit directly on american cars?​
 
How much shorter is it than the original stock one???

I'm not sure since the one I have is their prototype with the smaller diameter mounting flange. Mine required a bushing. Maybe someone who has bought the 2947 will speak up.

Whadduya askin' me for???

No, we have an old used one, that was a little loose. We bought a new clutch and fan from mancini, and it's less than 14" from the radiator fins, and we only have a two row....

I could measure it, but we need to agree on how to measure so our measurements are comparable (apples to apples).

I will have to dig it up and see if I can find a way that the total depth can be measured easily...
 
Put it on your bench with the mounting flange flat on the bench. Put a straight edge on the highest point and measure down to the bench. Easy enough... Then subtract that measurement from 2.71".

Just a note FWIW. Here might be a good example for the 3/4" fan to radiator clearance recommendation in the MP book..........

I`ve got one that is 3 1/4" tall, w/ supossedly a 7 blade hemi fan on it. it`s too tall for my set up. think the new one might work !!
 
I'm getting 2.95" for our stock e-body one and 3.046" for the new Mancini one...

I'm not sure that will get me to 3/4", but may be just under...

Or maybe go with a solid fan and see if I can find a short spacer...
 
I'll have to remeasure the space I have when my car gets out of the body shop to see which I need. I'm guessing the bushing went on the centering pin?

I measured off my water pump pulley snout fwd to my aluminum radiator that was made by (quality engineered products) and had 3&1/4" so the shaguar one will give me approx 3/4" clearance if its 2.61" i like the idea of the heavy duty one, however i would like the cushion of a bit more clearance.

very nice radiator. Stamped aluminum tanks. Mine was made for 73-76 A body needed it that way for the inlet and outlet required for my 78 360, and 74 318. I cut off the late model 73 up aluminum mount flanges, and fabricated new flanges from same thickness .125" aluminum sheet with mount holes to fit my 1967 radiator support, i glued them in place with jb weld and clamped with equally spaced cleco pins. Afterwards i drilled out the cleco pin holes with a #21 drill, and installed MS20470AD-5 button head aircraft solid rivets. Between the rivets, and the JB weld i doubt i will have any flange mounts loosening up.

Being that my car was originally slant sux, and i am doing a V8 swap, i needed everything. So besides the shaguar fan clutch, i am looking at the flexalite #5718 which is a 18" diameter 6 blade fan that works with a fan clutch unit. I am wondering if that will be a sufficient diameter fan. Ultimately i plan on a 400hp 360. For now prob a mild 318 They list it in 17", 18", and 19" diameters.

Mine is a 72 dart. It had a /6 now a 340 with a champion 3 core radiator. I have the new hayden clutch and it gives me a little over a 1/2 inch. I also have a motor mount swap kit not sure what brand. I hope that helps
