Before I scour the internet I thought I'd ask here first. Building a mild to factory 67 440 4-speed GTX and was thinking of using a 7-blade clutch fan vs a solid 7-blade fan. I think factory it would have had the clutch fan? but, what are the benefits of a clutch fan over a solid? or are there any really? Thanks info all.

Hi Mike, Gotta be a clutch fan every Time! Solid fans are noisy and rob horsepower... Most folks are going Ali rad and electric fans these days...

Why not take a little more load off the engine with the clutch? There is no down side to it other than the initial cost.
Master, again and still

Clutch it is! Thanks everyone. If using mechanical fan then yes clutch is best , and more importantly a proper shroud

Recently someone was telling me there are two different kinds of fan clutch’s? The kind you get from Hayden and the one you get from Tonys mopar parts? I forget what that person called each but they said they behaved completely differently. The one from Tonys will cool better. Anyone have an insight into what the differences were again? If any? Thanks guys.
Ive got the heavy duty short hayden version on my 67 GTX. It cooled better then the fixed fan. My vote is for the fan clutch.

Damn it, now I'm feeling like I need to get one for my Power Wagon. I was fine without before this thread.

FFS's electric.Try ZERO horsepower loss. What is wrong with you people? Throw 8 pounds of dead weight and 5 less hp in the scrap metal pile where it belongs: electric fans have been doing the job since the 80's.

This graph show the viscous clutch on the original Mopar 340 V8 Doubtful, the 340 isn't a 5.7L. More likely it's a SBC.

I dont worry about any wind noise from the fan. I run a 7 blade Chrysler steel fan no clutch with a clean good running rad with stroud and a 160 high flow state and mated water pump and housing. The hemi runs at 163 Deg. in any heat. If you are going to run the clutch on the fan buy new. .
