whats correct fan and clutch #s for 68 hurst olds ?

Allan R

I know the 68 Hurst was special, but I only have information from GM about the stock parts. If the cooling system was changed at Hurst these numbers may not be right, but here's what I have:

The fan is listed in GM Parts group 1.064 - part number 393996 (5 Blade)
The clutch is listed as Parts group 1.050 - part number 342754

The opinion corner:
My car originally came with a 4 blade fixed fan and lower volume water pump. It has been converted to HD water pump with 6 blade fan/clutch and fan shroud (I also had to change the water pump pulley). Unless you're going for concours points judging, I would go with best available aftermarket clutch - way cheaper than OEM NOS.

i guess you have a 68 hurst olds? i just bought one it has a fixed fan and no ac but it hit the shrould and previos owner cut it i thougt all h/o s had aluminum clutch ,fans this car is very original otherwise and was not hit i think org went bad and this was installed

A fan clutch would have a six bladed fan attatcherd to it...PN 401372...a seven blade fan PN 393996...'69 Hurst uses PN 406016

Don't forget that it's a specially calibrated viscous fan clutch.
Beats me what fan they used on the 455.
Have one vote for a five blade and one for a six blade.
The pic of the engine in the brochure shows a seven blade?

Thread HiJack:

I've not seen that ad before. I love that tagline: "Seeing is believing...Owning is unreal"

I'd like to get ahold of the advertising company that Olds used in the 70's, '80's and 90's and bitchslap each and every person there.

Olds should have hired whoever was doing Demmer's advertising in '68.

End Thread HiJack.

I dont remember that one. Thanks for putting that one on for us.

That's the inside of the 68 H/O sales brochure, I believe.

A six or seven bladed fan would have a clutch from the factory...different diameters too, 19 inch and 19 1/2 ?... one with a spacer is probably an after market item the fan in the pic is a seven blade with clutch.

Uh guys, why speculate, when you can look it up. Wild About Cars has all the AMA specifications for Oldsmobiles from 1964-72, and there is a specific spec for the 1968 Hurst/Olds at: http://wildaboutcarsonline.com/cgi-b...=9950359910638

The specs are: 6 blade; staggered; 18" with clutch. It even gives the reduction ratio for a/c and non a/c cars.

1969 is also listed at http://wildaboutcarsonline.com/cgi-b...=9940359910638

and the 69 at: http://wildaboutcarsonline.com/cgi-b...=9910335326553

The 69 page has the original "reprint" from 1969 Motor Trend as well. All ads and brochures on the site are downloadable AND have been restored to their original condition.
