Correct clutch and flywheel for M5R2 v6 adapt to 302W

[corerftech]

I decided on one of the two V8 swaps I am in the process of:
To stick with a manual trans.
I procured and M5R2 for a stock Explorer engine yesterday here in TN, 90k miles, its like new!
Still need a slip yoke!! thats a request if someoen has one.

Nonetheless:

As I have concluded (and I am asking for confirmation), I should be using a Mustang flywheel (50oz), a mustang 10.5 inch clutch and a M5R2 4.2V6 Slave/to bearing systems.
That gets me a 157 tooth FW with correct imbalance, two bolt long-nose starter (not explorer, maybe mustang??), proper slave for the trans and correct friction and PP for the flywheel.

I remember seeing somethign about cutting the input shaft slightly shorter for teh application but I have read too much recenlty and may be confusing the situation.

The spline input shaft on my trans is 10
The 5.0 F150 (ala 1995), M5R2 is also 10 spline, 11 inch clutch
The 4.2v6 F150 (ala 2003 my year trans) is 10 spline but 11.5 inch clutch
The 1995 Mustang 5.0, 10 spline, 10.5 inch.

FW:
Mustang as above, 157T, 50 ounce
F150/5.0L as above, 164T, no imbalance specified (problem)
F-150/4.2L as above, 164T and again no imbalance (major problem)

From that it appears: Mustang FW/Clutch and V6 Slave is the ticket.

Many thank in advance.

Hey Mike,

I had blindly bought and returned numerous clutch/flywheel combos from my local AAP. The only combo that worked was the clutch and flywheel from a 91 F150 (5.0, of course). It has the 50z balance you’ll need.

I went with the carquest brand, and it worked out fine.

Also, what starter motor did you end up going with?

 

[bobbywalter]

You match it.


Best is all 150. Starter...clutch and flywheel package.

To whatever balance

If using the F-150 setup you will either have to have a M5OD 5.0/5.8 seperator plate or carefully enlarge the hole for the starter in whatever else plate you have to fit your starter.

SBF Engine Seperator Plates

The whole thing came about when I tried to reuse the 4.2 seperator plate I got with my M5ODR2 with a '96 302 starter. The starter hole was just barely too small. The plate from my C5 was identical but didn't have a neat little foam seal around the crank. Faced with the rather terrifying...

Planned on a summit universal plate that has a double cutout for either starter. I couldn’t find an oem plate

Having trouble finding a 150 5.0 starter that doesn’t need remote solenoid. Any particular year I should shoot for?

157 or 164

It appears (and I am not representing this as absolute fact) that the v6 M5R2 with 10 spline input shaft can marry to any 10 spline clutch. That is my trans model. For the sake of “aftermarket” (not that the M5R2 is up to any power enhancement) clutch availability (and flywheel, etc) The list I compiled has the benefits of mustang 5.0 parts with the stock 150/v6 slave and of course the Mustang starter or any other 157 tooth model that crosses. I found a slightly improved grip pressure plate and disc by Zoom for the Mustang that I intend to go with.
So it’s all 1990ish Mustang except trans and slave and pilot bearing. The slave is same device for 150/5.0 or 4.2l application. BTW: slip yoke is same too. F65Z 4841-BC, I couldn’t find one used, and I mean like hens teeth. Vintage Parts had two NIB 1990s production, I nabbed one cheap! Else everyone wants $125 for a yoke. Eat me for that money!

$18.00 two day air delivery. Amazing company! Excellent customer service. You just need the FoMoCo part number or your dead in water. And I called my “friendly” local ford dealership to coerce the part number from them.

Mustangs had two different input shaft splines so the 10 is what fits the M5R2 truck trans.
Unsure if that helps clarify my list and the fitment.
I’m sure its fully tinkertoys. Match spline and flywheel diameter to trans, match pilot bearing ID to the trans shaft OD, match FW offset weight to engine and slave to trans. Starter is simply tooth count by way of original application/donor. The rest figures itself out.

The input shaft is different for different trannies that fit the Windsor, the bearing needs to match the input shaft OD.

I’m sure there are about 31.6 ways to fry this egg. There is a larger diameter truck 11.5 inch flywheel on the 150/5.0 and it’s heavier. The Mustang should behave like a lightened flywheel ( 10.5 inch) and rev a bit faster than the 150 version.
Another reason I am going with Mustang hardware over the 150 parts.

I run the 90 mark 7 starter.


It is not the same as the truck.. in the AOD 164 application it was fine...and a zf.

Biggest thing is to match flywheel and spacer plate.

I would run all 1992 150 stuff if you want the mini starter. Spacer flywheel starter.

Those are 11 in.

 

[bobbywalter]

And to be clear.

The m5odr2....as far as I know and have used.....is set up for a 164 flywheel.

So ..you want mustang shit....you need a mustang trans and set yourself up to run a shift fork...

To test if what you have works...put the 157 tooth spacer plate on the trans and see if you have bothy holes for the starter.

If it don't line up ...then it won't work right

BW, just researched everything you wrote.
I completely missed the Big Bellhousing/Big Flywheel fact.
So…… f150 parts it is.

Appreciate the correction before my parts order.

Correct, for the M5R2, I ended up with the 164T flywheel. It’s heavier than hell, and just barely clears the bell housing, but wit will work.

I’m just narrowing down which starter fits up and will actually turn the flywheel. The one that “worked” needed a remote solenoid and I’d rather not mock that up.

The ‘90MKVII starter works! Thanks!

No. You want all 150 92 manual


They are different in engagement depth.

The 135 is auto....the 136 is manual


Summit has it under AC,s number 88877136
