Need a 250 Flywheel

[Nathan289]

Hello,

Yes I'm at it again.. I wanted more performance but wanted to keep the six so I'm building a neat little 250ci motor..

I've long rodded the engine with connecting rods from a 2.5L Ford taurus engine.. yea they put 4 bangers in tauruses.. These rods are .100" longer than the stock 250 rods.. I have .150" to zero deck not counting headgasket thickness..

I'm having a custom ground camshaft made for it as I want to try a split duration cam and nobody makes it like I want it.

The problem I'm having is finding a flywheel for it.. I want to keep my five speed so I need a 250 flywheel..

I've heard that I can take a 289/302 flywheel and zero balance it for the six but I'd rather not..

Can anyone help the falcon nut?

Thank you,
Nathan

Ford did have a brief period of zero balance 302s. They went from 28 to 0 and then to 50. I'm no expert on the 250 six but if a standard small block V8 flywheel fits, you can buy a new zero balance unit.

The Ford Racing catalog lists a billet 157 tooth flywheel with zero ballance. The part number is M-6375-D302.

Summit Racing has it online.

Pat,
yes I can use a SBF flywheel had to do a little more research but I havent gotten anyone to tell me no I can't.. So I can use a zero balance flywheel..

I found one on E-bay for a fair price.. was hoping for a Fomoco orginal to save even more coin and take any guess work out of it..

Ok I found a flywheel...

Now I need a bell housing.. The one I have might not work.. I have a D1TE-6394-aa which fits a 351 but looks to be a truck bell which is too deep..

Any body know where to find a 6 bolt SBF Bell??

I havent looked at e-bay yet..

I might be selling one soon though

These guys should have something.

You could probably source one from a T5 equipped 5.0 Mustang.

[Nathan289]

I could.. I've been toying with the idea of hydraulic clutch..

But in the mean time I was thinking of using the z-bar system.. but I need to check if the 250 block has the boss for the pivot of if the bell has the pivot for the z-bar..

I'll research hydraulic clutches.. I'm only in the parts gathering stage as I'm waiting for the machine work to be finished before i start assembly and disassembly..

A hydraulic clutch would be nice. You could also get one of the cable clutch kits from the website I posted earlier.

I've heard of people using Mazda clutch masters. I'm not sure what model. Maybe the 323?

For the slave, you should be able to use this.
http://www.amazon.com/Raybestos-SC33721-Clutch-Cylinder-Assembly/dp/B000CPAOSQ

It attaches using the bellhousing to engine bolts. It pushed to the rear. You should be able to find one at a local Napa store.

[Nathan289]

I prefer my local O'reilly. Only because I'm a manager at one..:doh:
atleast thats how I feel after work sometimes..

My friend jeff said add hydraulic to his 64 wasn't that difficult. but then he has no shock towers so theres lots of room..

I'd love to just use a t-5 bell but those bells use a fork that pulls instead of push.. If I could find a push t-5 bell I'd have the best of both worlds..

I dont care for the big loop that the clutch cable set up creates.. atleast the mustang kits I looked at anyways..

I agree. It looks kinda funny. I have a friend with one in a 69 Mustang. It has a nice feel.

I don't think you will have a problem fitting the master. They are quite small.

[Nathan289]

I need to do more research..

The Bell I have is a D1TA-6394-AA which according to David Kee is a 351 Bell but I find lots (the majority) of the ebay bells are the same part number and they have them listed for every engine under the sun..

I measured the depth and its not a truck bell which means I should be able to use it..

So I'm confused, too much questionable info out there..

Nathan

The 351W uses the same bolt pattern as a six bolt 289, and 302. As long as the pivot is right and the depth is okay it should work.

Wilwood has a universal pull style slave that you could use. It's not as cheap as that Raybestos though.

[Nathan289]

I wonder if Speedway has a universal pull style slave..

It seems that t-5 bells are easier to find than the older stuff.
I could build a hydraulic clutch using a pull slave and be shifting in comfort.. though I'll probably have to fab mounting brackets..

Nathan

Still reading up on bell hosings

[pbrown]

Back to bell housings. You can also use a stock 250 bell or a four speed bell from a 289/302/351W. You would then just need the T5 adapter plate.

Here is the adapter for a T5 to 4speed bell.

This link will take you to a list of adapter plates from Modern Driveline.

Boy the Maverick forums has lots of good info..

The bell was used in a truck or 351C cars
It is a 164 tooth bell which allows me to use a 164 tooth flywheel (new search) but also allows me to run an 11" clutch.. If I have room in the engine compartment I can use the bell, but I may need a BFH to make it fit:mad:

Back to my reading..

I would stick to the 157T bells. You'll need a much smaller hammer. A 10.5" clutch will be more than enough behind a 250 in such a light car.

[Nathan289]

I'm agreeing with you there.. so e-bay here comes another d1ta-6394-aa..
If I could find a 250 bell I'd be all over it like stink on ****.. I'll keep searching..

Thanks for the Ford six link.. looks like Daze cars might have some info on hydraulic clutch stuff..
Bruce at Modern driveline is a great guy.. I'll be buying an adapter from him and selling the one I no longer need.. I have a t-5 adapter for the small 2.77 bell for sale in the near future..

Well I have no work tomorrow so maybe a junkyard crwal is in order.. nobody ever wants the 6 cylinder stuff maybe I'll get lucky and there will be a fresh maverick out there with a 250 and a 3.03 trans..

Nathan

[pbrown]

A four speed manual 289/302/351 car would work to. It's probably the same bell.

Good luck on the search.

[Nathan289]

I've been told that a p/n c5aa-6394-b will work..
Basiclly any 157 or 10" 6bolt bell will work..

I need to have a garage sale.. too many falcon parts..

When is the monroe swap meet?? Roger... I have another 2.77 tranny for you:BIRTHDAY:

I'll just keep searching and investigate the hydraulic set up..

Thanks for the help pat..

You'd get a kick out of this engine if I ever put the 3 dueces on it..

Nathan

[Nathan289]

Well I thought I found gold only to get home and find out that I'm one part number off.. I found a C5TA-6394-A which is from a Truck with a 302..(needs to be c5aa-6394-a)
I pulled the bell and counted the flywheel teeth and it has 164 teeth..
I bought it anyways because maybe it will still work and it will but I have to go with the bigger flywheel and might have firewall issues..


So my search continues... and somebody said the bells for the 164 tooth flywheel is rare.. B.S. I have two now..

Nathan

That's officially a collection now!

[Nathan289]

Yeah if you add the 2.77 bell I have and the c-4 bell
I really do have a collection.. The c-4 was orginally behind the 250ci..

So I have a C-4 trans and another 2.77 trans laying around..
I also have an orginal 64 falcon six cylinder rear and a 8" rear from a 65 comet..

Plus two complete front ends one six and one v-8...

I'm collecting falcon parts... Next years swap meet should be good for you guys..
