91 5.0 into something else
(Click here to view the original thread with full colors/images)

Posted by: aaronfeeney

ive got a 91 stang 5.0 going into a 1960 willlys wagon ..im using the mid 70's t-18 4 sp.i found someone to build a flywheel that will work on both ends but "would it be cheaper to use the 91 flywheel bellhousing and complete clutch assy,& starter?????? or the 250$ custom flywheel???????

Are you swapping the fuel injection set up over to the wagon as well? Since this is going to be an involved custom swap I would probably just use the mustang stuff. You will probably have a fun time trying to make things fit as it is, so I would use as many common parts as I can.

what did the T-18 come out of? wasn't that a truck tranny?

The big things to figure out...
1. Does the stock bellhousing place the tranny at the right distance for the input shaft to seat into the pilot bushing properly?
2. Can you get a clutch in the right diameter for the flywheel, and have the proper diameter/spline count in it's hub, for the input shaft?
3. Do you have a clutch fork that will hinge in the bellhousing properly, and connect to the clutch linkage properly? The Stang had a cable operated clutch.
4. Does the Inside diameter of the pilot bushing match the outside diameter of the pilot shaft?
5. Most late model Ford Trucks with 5.0/5.8L engines had a slightly larger flywheel than the cars. Would the flywheel/bellhousing work in your application?

You can try some place like Advanced Adapters and see if the make a setup to do what you're doing, if nothing else.

The thing to figure out is, WHY??
Anyway, if you want this to ever be a 4X4, you'd better not try the POS T-5 that Mustangs came with (in 91). Clearly I don't know what the plan is, but consider some basic things with your planning. How heavy, what "usage" is planned, how powerful and how often driven? All those should play a big role in a custom setup like this.

i've got a bellhousing for a smallblock ford truck then going to my trans granny 4-speed out of a chevy truck with a 205 transfur case . i'm using a stock mustang flywheel ,starter. and a hydralic clutch setup from afco racing .

Nothing like making things more difficult! If anything ever breaks, you're gonna wish you never did this build. arts are mismatched and most places are going to need to see a part before being able to help locate anythign you may need later. You might wanna see about updating to a Ford hydraulic clutch system though, just to help reduce the list of manufacturers.

ive already done the custom work w older 302,flywheel and clutch are good to go ...91 bronco flywheel ,clutch stuff and bell housingw my own bolt holes to fit trans...only thing left is to install engine and re wire engine compartment w/mustang harness and computer..i am used to the custom thing,i am running 302,t-18 from jeepand dana 20 x-fer case,w/my own drive lines and gm 10 bolt f,,,gm 12 bolt w/locker in rear..ive owned and customized this rig for 12 years ..just looking for advice on what electronic goodies need to stay and what can go..ive also done a lot of custom manufacturing of running gear and steering parts for 4x4,probably of no interest to hot rodders

the trick is not to break stuff and if you do build it bigger so it will never happen again

I can break anything on wheels! Heck,, most of us can. Anyway, this project has "I'll be beat on heartily," written all over it... :btg:

So then the only real problem you are asking about is the flywheel balance and starter compatability?

that is the part in question at the moment ..ive found several places to get ,,,the 50 oz.flywheel in 157 teeth..but i am now wondering if i can find a starter that will go in my old bellhousing with the 164 tooth flywheel????

Posted by: aaronfeeney

and yes itllrun,this project has been beat on heartily and will continue to take a beating

The starter should work, 157 or 164T. I've never thought much about it, but I'm all but positive they're the same unit. In fact, I am. They list the AOD as a 164T flexplate and the T-5 as a 157T flywheel, and they do use the same starter for both. Evidently you can use the same old starter. I'd get a 1992-5 unit though, because they're smaller, lighter, and have greater torque.

ahh thx ...i just pulled my old engine and it has the 164 tooth ring gear anyhow... you say the 5 sp flywheel is 157? the problem i see w/the starter is that a 164 tooth is a larger diameter than the 157 tooth and i cant see how the starter gear can mesh w/either one.unless the 5 sp has a different location for the staeter ie..a little closer to the flywheel..now that ive checked i need a 164 tooth flywheel for 91 5.0...

Posted by: Grape Ape

If your original tranny was an AOD, it is a 164T. If it's a 5speed, it was a 157T. The location might be how they did it, but they did use the same starter. I had an AOD in my 91 Mustang and swapped to a T-5 and used the same starter.. Then again, I also used the same starter with a GM tranny.. heh. I have the same starter in my C6 now, and used it with my C4 too. I did upgrade to the 92 or 93, whichever, but only for the size and weight diff. So if you want the 164T, just get one for an automatic 91 Mustang 5.0 and you're all set. The 164T is definitely a larger flexplate than the 157T.

but i am bolting it to a 1979 4-speed so ill need a flywheel not flex-plate .but i need 164 teeth or a starter that will work with my "old"bellhousing and 157 teeth...does anyone know if the late model 5.0l trucks had the 164 tooth "flywheel"w their 5 speed??????

Posted by: Grape Ape

Not sure which flexplate or flywheel they used, but the starter was different, so that might explain a different fit. They did offer an 11" clutch on the trucks though, so look into that flywheel.

Posted by: An11SecRanger

I can't think of a 164 tooth, for a late model 5.0 (or any 5.0, with a maunaul tranny).
I'd say there's 1 option:
Get one made (from a company like reactor Plates {sp)

Then again, if you can find a 164th flywheel that'll bolt to your crank, you can always add weight.
The difference (for starter fit) is the location of the starter in the bellhousing.
It'llrun gets the bonehead of the day (or week) award for not remembering this! He has held the plates (dust covers) in his hands and said, "I need this one".
The trucks used a completely different tranny, so the starter may be different, just due to that reason.
However, if they used a 164th flywheel (I never checked), it should still work with your 164th bellhousing. In that case, problem solved.

Some mid 60's Fords/Mercs used 164 tooth flywheel on smallblocks. I know my 64 Cyclone (289) did. But it would have to be rebalanced for the later motor. At one time FRP made a 164 tooth flywheel to use a late model motor with the older bellhousing/11" clutch. They may still.

thx guys i found a place that will match my old style 164 tooth to the newer flexplate ..i have to hand them both and they will match balance them,, with new ring gear surface and balance its 100$

i'll still check on the late modewl truck flywheel ...it may be cheaper...

Posted by: Grape Ape

Take the $100 deal and go. At least then, you'll know it works. Or at least you'dbetter know, or that's a wasted $100 !

Posted by: aaronfeeney

got 1 better 1990 ford bronco 5.0 5 sp came stock with a 50 oz imbalance 164 tooth flywheel,and centerforce offers a lever pressure plate ...problem solved ...thx guys,,,flywheel is 39.99 exchange
