Hello folks, I know there are many threads on here devoted to performance clutch packages; - But some of the parts are hard to get and some of these parts have come back with mixed reviews for one reason or another..
Also I am not sure Part #'s for the other clutch threads are clearly provided.
With some posts I have read you have to call the clutch company and then talk to a tech guy at the - then they make the parts for you.. And also which stage to get seems to be a concern as well.
Hopefully I can help with a few concerns:
Which Clutch / Pressure plate diameter to choose? -
Stock type borg&beck Pressure plates exploding at High RPM's and not providing hardly any holding power behind a modified slant or possibly a heavier car / truck..
I am Documenting My current clutch install into My daily driver 79 Volare(duster) to help inform folks about what is available and what will swap.
I have never attempted to contact Spec or any other clutch company - I am just using some McLeod Parts That I have used in my '69 Dart For over 10,000 Miles and with well over 250 Dragstrip Launches on a ~300 HP engine in a 3400# Car. These Parts work - I have tortured and tested them that's why I was so happy to find them available (even though I thought they were discontinued)!
At the time of this writing I found these parts seem to be available through summit/ Jegs as a 1-2 Week order - And they came in! (maybe they are tucked away in a warehouse somewhere??) Even though McLeod does not officially list these parts ontheir website
Here is all the shimmy on the Part #'s you'll need to do this setup:
-McLeod # 260826 10" 1x23 Dual Friction Ford Clutch Disc
-McLeod # 360116 Ford / Mazda 10 Press. Plate
-Stock Throwout bearing.
-You will need a flywheel with a ford 10" pressure Plate mounting holes drilled on it.. Most likely your stock flywheel is not a good one to use for this..
Get the McLeod one Part # 464001 (it Fits stock slant pressure plates and the 10" ford one as well) It is SFI approved too
Pics of what We are dealing with here:
New Pressure Plate and dual friction disc (10")
This is a diaphragm Pressure plate - not a 3 finger one like a stocker - It will require a 3/8 to 1/2" spacer to be fabricated to move the clutch lever / TO bearing closer to the fingers - More on that later.
When I did this install of this package on the dart back in 2006, I had some interference issues with the clutch disc hanging up on the Press. plate on the inner sides of the mounting tabs - i will address this mod later in the thread when I do the install.
Here are the tabs:
Notice how close the mounting tab protrudes into the Pressure ring space:
I like the quality / design of the disc:
Some people have noted issues with the Ford 1X23" Splines somehow being different than the chrysler ones - i have NEVER had any issues here;
Shots of me test fitting The disc on both a spare 833 and an old 3 speed input shaft that I will use as an alignment tool:

More to follow!
