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?

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.

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

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

      There's an outfit in Fort Wayne, In that can make you one, also one in South Bend,In. What exactly is the problem with what you ordered, and what do you want?

The bronco had the smaller input trany and so the pressure plate fingers are closer together than those of the large input.  I was just taking a chance here.

The one I ordered from Mac's, to fit '48 - '64 trucks, was for the smaller input transmission.  They had no alternative.  The picture representing the part looks exactly like the part I need.

Ideally I would like something with a little more holding power.

The clutch would slip on hard acceleration.  At disassembly I found that the flywheel had started to crack which, no doubt, contributed to the slip.  The pressure plate wore uneven.  The 3 fingers were not at the same height so the throwout bearing pushed on two fingers to start out.  I did not notice this when it was assembled.  The 1/3 of the pressure plate corresponding to the third finger has hot spots so it has probably warped some, also contributing to the slip.

Because of my speed addiction, the engine has been modified much more than I intended 5 months ago.  I don't think the stock clutch will act favorably but I don't know what the stock clutch is designed to handle.

Have you any experience with either of those outfits?  I may go that route if stock doesn't hold.

Look for a larger truck application, I have a 58 F500 w/272 and have a few transmissions around that came out of big trucks with a PTO and They all have the 11" pattern with the     1 3/8 x 10 spline. I am sure it is the same setup you are looking for.

When I got the combination for my T10 conversion, I went to NAPA and looked through their applications and compared part numbers until I found the same part numbers (I.E. looked at 63 galaxie pressure plate numbers and matched them to a 292 truck pressure plate number) then found a kit using that number and the matching clutch and throwout bearing to fit the spline of the transmission.

          OK, you need an 11 inch clutch, Have you faced the  flywheel to remove the heat cracking? If the flywheel itself has actually started to crack, REPLACE it. You do not want to see what happens when a flywheel breaks. You now have anoption in the pressure plate department. There's three styles available, Borg and Beck, Long or Diaphragm. Ford generally used the Long style. The diaphragm has a nice light feel, The B&B is a good compromise. I run a diaphragm with a Kevlar disc in the red car, works pretty well with stock type tires. Don't think it would hold slicks.

 Next, is simple, order a clutch disc for an 11 inch pressure plate with whatever size and spline count your tranny is. I'd suggest a McCloud or Ram, dual friction. Use new everything, grade 8 bolts for the pressure plate, new throwout, check the pilot, make sure it's not worn out, also check the throwout arm for straightness. Make sure the pressure plate and disc are designed for each other. the disc thickness is a factor.

        Have no problem with that issue on mine, but it's a 1 1/16" 10 and I used the diaphragm Press plate. The only issue is that I have to run with very minimal throwout to finger clearance in order to have enough travel in the linkage. I can check to see what they have at SB clutch if you want. I would also recommend you pick the phone up and call Ram or John and see what they have.

I already spoke with John.  He wasn't sure what would work for the truck.

I haven't tried to contact Ram.

The one from Carolina will be here Tuesday.  We'll see if it's correct.
