I think I'm going to get a clutch kit for a big block to use with the 292 (1 3/8' 10 spline input shaft), say a '66 fairlane 390 kit. Does anyone know if the throwout bearing will work with the pickup clutch fork.

Didn't the 390's use the smaller input shaft?? When I got a clutch kit for my toploader (small input shaft) against my 312, the kit (which was for some later Ford ) the throwout bearing fit ok. This was a sedan fork, not a truck though.

The throw out bearing for a small input transmission will not work with the 1 3/8" input transmission.  A majority of the car big blocks were small input until you got into the Cobra Jets or the Boss engines.  As Paul mentioned, the 66 Fairlane with the 390 was a small input tranny.  I'm assuming you've got a 1 3/8" input tranny that you're dealing with?

It's a 1 3/8" 10 spline 3 speed.  I think its the standard pick-up transmission.  I'm just browsing through the online Summit catalog.  It comes up with 1 3/8 options for the 390 fairlanes.  The throwout bearings look different though.  They have two clips on the back.

But I was just looking at it again and noticed that the throwout bearing is not included.  I found one that looks right.  So I'll try it out.

Do you think that a diaphragm style pressure plate will cause any adjustment issues?

You shouldn't see any differences in adjustment.  I've got a diaphragm style pressure plate behind the 272 in my '55 and it reacts just like the long finger style it replaced.

Hopefully I won't have any issues.



Which other engines is the pilot bearing shared with? Summit doesn't have a listing for the Y.

Well,

I tried the clutch kit above and the bolt pattern of the pressure plate does not match that of the flywheel.  I have the Billet steel flywheel from JM that should be drilled for the original style and diaphragm style.  I verified that the stock pp lines up correctly.

Does anyone know of something that will fit?  I think I'll need something that is better than stock.  I should be in the neighborhood of 320hp with the new engine.

How is the Zoom stuff?  That is the only company with a specific application to the truck.  Here's a link  Zoom Clutch

Hi Charlie,

What size pressure plate bolt patterns are on the flywheel you have?

I used a truck flywheel with the 11" truck bolt pattern and bought a clutch and pressure plate for a 1963 galaxie with the 406 to use with a T10 transmision and everything bolted and splined up perfect. I don't remember if it used the 1 3/8 diameter spline or the 1 1/8 though, I have to get ready for a wedding but can check tomorrow and have part numbers from NAPA for the combination.

Also, I pm you about the VS57, Please let me know as I was away for a week.

Thanks, Bill

The flywheel has the stock 11" bolt pattern - my old 11" pressure plate lines up with the holes. I think it also has a later diaphragm style 10" pattern. The 11" pattern has 5/16" threads. The other pattern has 8mm threads with dowl holes. I'll research the 406 clutch. Thanks for the lead.

Do you think the stock 11" will work? The axle is 3.70 or 3.89. Vehicle ID plate says 3.70 but there is a partially smashed tag on the pumpkin that looks like it reads 3.89. Plus it's a truck so there isn't much clutch slipping traction anyway. I don't pull anything with it.



I'm not having much luck finding anything else.
