Hi forum. Since I have the engine out of the car atm, I can inspect everything. I am fighting with myself whether or not to totally refurb the engine with all new stuff!🤠👍🍹🍻

The flywheel has a few chipped teeth…..afaict, the flywheel is 164 tooth. (4sp/351cj).
What flywheel can you fellas recommend? I just want a standard OE flywheel.
I found a Pioneer flywheel over at Summit…FW-113. Reasonable price….
What ‘balance’ do I need? External, 28oz…..is my guess…please confirm. Thanks.
Lemme’ know…👍

The original flywheel is part number C6TZ-6375-C which was used on many applications for many years, including the 1972 351CJ.  The Pioneer website shows that FW-113 interchanges with Ford E8TZ-6375-C


NDP shows that E8TZ-6375-C is interchangeable with C6TZ-6375-C so it should be good.

A machine shop can press on a new ring gear if that’s practical for your situation. When I had my flywheel surfaced I didn’t know it was a separate piece. The shop called and said they could just flip my ring and re-install to get on the “fresh” side of the teeth. I didn’t have any damaged teeth, just normal wear.

Yes…I was actually contemplating just that. The clutch and flywheel look and feel good and smooth. No need to change them.
A new ring gear is easily doable. A ‘flip’ is the cheapest option. Free basically!👍 
My engine ran pretty good…I am just doing needed ‘basic’ service. Timing chain, oil pump, valves, gaskets, cleaning, painting, etc……I am nearly finished…just small items to go.
I live in Denmark……machine shops that ‘know’ these cars and ‘can do it’, can be counted on 2 fingers!

My flywheel is smooth and nice. No gouges and very even wear(if any). I will reuse it. (Original FoMoCo flywheel👍🍹). I tapped of the ring gear…..very easy…..a punch and 4-5 taps around the ring and it came of.
I have ordered a new 164 tooth ring gear. The new ring gear will be heated and fitted.
I have cleaned up the flywheel nicely and coated it with some light oil. (To prevent rust while I wait for some parts) This oil will of course get cleaned off before install.👍
Now to make a clutch decision!🍻🤿

I’m no clutch expert, but if you’re replacing your friction disc, you may want to get your flywheel machined to help with break in. Maybe even a good scuff with a disc sander? Of course, if you’re not replacing your pressure plate either it might not be an issue.

Now I have something puzzling me. Rockauto is not listing the correct clutch flywheel kits anymore for the 72-74 four speed cars. 

I looked on pioneer and had to look under 1970 Mustang 351 (Doesn't say C or W) and got back:


PART NUMBER : FW-193

Original Equipment (OE) Part Interchange

OEM: C5AZ-6375K

My original Ford flywheel that I am still using has this cast and stamped on it:

Cast# C5AE 6380-E
Stamped# C7TE-A

Sadly, days of automotive machine shops in the USA are getting slimmer as time marches forward.
Especially the shops that know 50 year old Ford V8's.

Ok guys…Different route. The original flywheel was in great condition. The ring gear wasnt. 
I bought the Pioneer FRG-164N ring gear. It was a perfect fit! I cleaned the ring gear and flywheel mounting surfaces…..put the ring gear in the oven at max heat for 15min……and it just slipped on the flywheel…spun it a few rounds to seat it. Done. 
👍👍
