Greg,

The 17# stock flywheel, what does the crankshaft side look like. Just curious since there are two flywheel styles depending on car vs. truck/ forged vs. cast crank applications. Just want to see if you have the standard car one with out the "ring/ridge" or the truck flywheel.

Good info, keep it coming.

Here You Go DI...



These are shots of the backside of the Flywheel I pulled from the ca and had cut.... I am really not sure if it was originally from a cast engine or not.. THis car had a lockup 904 in it back on 2004 - Then I put the OD 833 in.. Nit sure where I got they flywheel.

That's a car flywheel, I've found a couple on 1978 F-bodies as well...

The truck/late units have a thick ring on the back side...(which seems to help motivate fat a-bodies off the line due to the extra weight...which was probably needed to get a fat truck off the line when the engine got strangled by emissions requirements).

Thanks for sharing! 8)

So when everyone says if you take a manual transmission over 5000 rpm its gonna come apart, what actually fails? Flywheel or the pressure plate?

Typically the pressure plate in the clutch cover fails first. Cast (iron and aluminum) flywheels are illegal under SCTA/BNI regulations for Bonneville and El Mirage. I ran my road race car over 6000 RPM and nothing failed, but it's risky.

I've done multiple 6000-6200 rpm clutch dumps on street tires and either the 9 1/4" stock clutch disc withers out or the kevlar disc takes on too much heat and just slides around....I haven't had a stock flywheel come apart yet, but I haven't pushed one to the "extreme" (gummy slicks, high rpm, puck clutch, lots of HP).

I think multiple 6000 RPM clutch dumps is the extreme on a stock set-up. I had done the same thing many ,many times . Mine exploded on street tires on the 1-2 shift. I am telling you, it ain't pretty. No way I would even consider using the stock stuff for high RPM shifts. I like walking too much. Do a search on Greg's 69 Dart and look at the pictures of his explosion. I had the twin explosion to his.

The Local McLeod Dealer sent my Flywheel back to get the correct Bolt pattern drilled on it.


I reccommend to call McLeod Directly to Order your flywhyeel and Tell them to Order part # 464001 but to drill it with a stock Borg & Beck Pattern (McLeod PP Pattern #3 in their Catalog), & that you will be using McLeod # 360116 as your pressure plate - Ask them to drill this Pattern on your flywheel too.

I didnt have this problem in 2006 when I ordered # 464001 Directly but This time i Did - Hopefully I can get this all buttoned up in a week or 2.

Well After all the waiting for McLeod To get the Flywheel drilled correctly I got all the parts back and assembled in the car.

I clearly did not have all this trouble back in 2006 when Red Roberts ran the McLeod company.

Here is the Remaining install:

The flywheel is Back With 3 bolt Patterns on it Now.
Image


It now has the Pattern to mount the Ford 10" Pressure Plate... YAY
Image


I choose To use ARP Pressure Plate Bolts..
Image


Image

These bolts come with Washers from ARP and They are listed for a Ford under ARP Part # 150-2201 - They would work with your stock Slant Flywheel too :-)
Image


Flywheel Installed - Used Some Red Locktite on the Threads.
Image


Image


Image


I will Use the Dinky Plastic Clutch alignment tool until I get the Press. Plate "Started" on the Flywheel.
Image


Image


Image


After I Get the bots started just enough to hold the PP down (finger tight)
I swap my clutch alignment tool to an old Input shaft.. I find this to be less hasslesome and the disc does not "slide" around and fall out of alignment with this tool.
Image


Image


Once I get the disc in good smooth alignment with the old input shaft Then I start to crank the PP down in a criss-cross Pattern (much like the lugnut tightening sequence..) but just a few turns at a time at each bolt until the entire PP is bolted flush to the Flywheel and exerting full clamp load. (this process is much like putting a drum head on a Drum)
Image


Image

All Tightened up Flush to flywheel.
Image


Image


Image


Remember the Clearance Notches I made HERE?
Here is Why I did that.. On the Dart the Clutch disc caught the Area of the PP near the bolt haed So A little clearance helps.
Image

When I first Test Fit the Bell Housing on I coundnt get it to sit flush against the block..

No Problem.. I shimmed the clutch fork pivot too close to the engine..

I removed one of the 3 Shims I made and clearance as good.
Image


Image


I originally Had a stack of 3 spacers in there. Now just using 2. (this could vary with different TO beareings etc.. By the way Use a New stock TO bearing it will work if you are still using ma mopar's Linkage system.
Image


One of the Bolts needed a bit of grinding so the Bellhousing would sit flat against the front of the trans Face.
Image

Greg thanks for the awesome write up with pics. I am putting a slant six with a 4 speed overdrive in my 48 Dodge Panel truck. The engine is going to to turbocharged, but nothing crazy. My question is, can I have the original flywheel redrilled without any issues? I'm just trying to save a few bucks, so I can get my hydraulic throwout bearing going as well. thanks

Hello, I have never tried to Put the Mazda/Ford 10" Pressure Plate Pattern on a Stock Slant Car Flywheel. I would imagine if you were using an 11" truck unit this would not e an issue.

You say with out Issues... Well this particular Pressure Plate Bolt pattern sits Very Far out on a stock Slant (car) flywheel.. the holes almost hit the Ring gear.. With The 2 Steel Flywheels (one in the Dart That Has had many High 14 Second Passes on it) this setup has never had any issues..

I do not know and Cannot speculate about the Stock Cast Flywheel holding up When the Holes are Drilled so near the outer edge of the Flywheel. I do know they hold up fine in steel.

If you continue this route, get the disc and Pressure Plate Part #'s Listed in the thread from Summit Racing and then take the Pressure Plate and Flywheel to a Very Competent & trustworthy Machinist to have the pattern drilled. It has to be centered spot on. I am not a machinist, Bu I know that if that part of the whole operation is messed up your project is shot.


Best of luck.

Greg

Wanted to resurrect this thread since the McLeod Ford/Mazda Pressure Plate doesn't seem to be available anymore. Any idea what the specific application in/was for, so we can cross-reference it with another PP?

Has anyone talked to Mcleod directly about this? Their online catalog leaves a little to be desired.

Ryan's PP was not in the catalog but they had it still. Hopefully this Ford set up is still available!!

Ya can still get the flywheel and clutch disc from summit. And one seller has the pressure plate on ebay. Im looking at $700 in just the clutch, flywheel, and p.p. that seems very high
