Viscous Fan and stock 383

[1969383S]

Can anyone confirm if the 4120758 package will fit with 088 or 065 radiator in a 1969 barracuda with stock 383 config. I have read that the clutch may be to long.

those clutches are to long for just about everything, i took back that kit wnt to the junk yard and found a 18" fan off of a old mopar and got a clutch for a 89 jag number i think is 2705??? and used it in my 68RR

2765 I think

Funny you say that. I had the viscous package on my 65 Valiant. It was close, but it fit.

Rob it seems all you read is much about them not fitting but no concrete proof.


Always seems to be someone that has either modified something or tried using on in a different car.


Would really like to hear from some one with a stock 383 Barracuda or Dart that has tried using one with the Factory 68 or 69 3 row radiator.

I do not think it will fit. I'm pretty sure I had to use a factory flex fan in my original 68 383 FS. The spacer is real short.

I will say my car was a 360, not a big block, so that may make a difference. It did however, have a custom 4 row radiator that was made using the old tanks and frame from the original radiator. But the extra rows ad to be installed going towards the engine, so that may have made up some of the difference of it being a small block. Why the heck Mopar doesn't make the unit more compact, I have no clue. I am sure it could be done.

Yes the Factory 7 blade Fan (2863213) used a .70 (1851960) spacer.

The set-up I used to run was a thin aftermarket flex with 1.5 inch spacer and front mounted electric pusher fan on an aftermarket 3 core radiator that was to large for the core support. That setup left the fan very close to the radiator.

Going back to an original radiator/shroud/fan with the restoration and the cost of the old parts is a much or more than the Viscous package so I was hoping to save a buck.

Any Idea how much space you had between the snout of the pump and the radiator?

I just went through the exact thing in my 69 383-S. I have the stock radiator (065) in it and the original k-member (engine in the stock location) The Mopar Performance clutch was at least 1/2 inch too long.

I went to the junkyard and found a used clutch out of a early 60's Chrysler 300 that fit perfectly. I it a little less than 1/2 inch clearance between the clutch and the radiator.

PS I measured the distance between the leading edge of the fan pulley and the radiator and it is approx 3 inches.

Hope that helps.

Thanks Rod,

Yes that answers the question directly! I will go with the 7 blade original...

Wish I could find an 065 in re-corable condition that was reasonably priced... I have an new in the box 088 and will use it unless one pops up in the near future.

I sold my new clutch on ebay and got a pretty good price on it. I really needed a clutch fan because I was running a direct drive fan and it very loud.

Anyhow, I have not seen a reasonably priced 65 radiator in a long time. The ones I Ebay I have seen have been 750 plus.

I have no idea. I sold the car in late 1999, so that was a while back. I do remember that it did not have much space between the radiator and front of the clutch at ALL. I think had I broken a motor mount, the fan could have gotten into the radiator. That's one reason why I always drill the driver's side mount clean through on all my biscuit mount stuff and run a bolt through it with a nut on the other side.

Rod answered my question.

I Agree about the through bolt on the drivers side biscuit.... Cheap insurance and better than a strap or other methods.
