- Today on Dead Dodge Garage, I show you how to modify a flywheel for an A833 four speed manual transmission to make it work with the factory Chrysler fuel injection on the Magnum 318 and 360. If you have access to (and knowledge of) a brake lathe, you can do this operation yourself - or feel free to involve your favorite machinist. Also in this video, cleaning and assembling a factory Hurst four speed shifter, and some other details of the four speed conversion in my ‘66 Charger.

I did a 4 speed swap into a 69 Valiant slant six. A little bit of fabrication to the Z bar bell housing pivot point as I recall, and having a reducer machined to adapt the transmission input bearing to the bell housing. Once I got the correct floor hump and A body shifter, it was very rewarding and made the car a lot of fun to drive.
For only one part of three, that's a lot of work!
Just wait until you see the amount of work in tomorrow’s video… OOF.
Ingenious .
I'm learning new things......things are cool
Magnum crank position sensor tone ring fits on early a-body flywheels with 9 inch clutch
I’ll be damned. That’s good to know - but to use that flywheel you’re stuck with the small clutch and bellhousing, I’m assuming? Or is it the same as the later 10.5” bell?
This is some funny stuff 🤣
In a 68 dart with a 318/904/7.25, swapping to a 833, will just a new yoke and conversion U Joint be needed? I assume the U joint size for the 904 won’t be the same as the one needed for the 833. This won’t be a permanent setup. It’ll be just until my 8 3/4 axle is together and ready. Since it’s the same length, it will be okay for a temp basis and being very careful to not explode the 7.25 axle.
No clutch dumps with traction for you. Haha. Actually, you probably won’t even need a conversion joint, all depending on the yoke you buy. There are small joint and big joint 727 yokes. If you do need the conversion joint, I believe it is a Moog/Precision/whoever else part number 347.
Well that’s very good to know. Yeah I’m planning my mediocrity in stages. Once I get my 8 3/4 axle together I’ll need another driveshaft or shorten this one. The small joint 727 yoke may be the ticket. I emailed Brewers as well to see what I need. It’ll be a turd but a slightly cooler turd after the 3 pedal solution has been applied.
How about taking a stock 5.9 magnum 143 tooth flywheel , removing the ring gear and having the outer circumference milled down to accept the 130 tooth ringgear? That seems to be a good alternative because I believe balance would be correct and the tone wheel to trigger the injection would also be already on the flywheel.
That flywheel accepts a larger truck clutch - 11”, or even bigger - that won’t fit the 10.5” bellhousing (easily, anyway) and won’t match the input spline of the A833. The tone wheel is built into the surface you are suggesting to turn down - so one could only turn down part of it, similar to what I do with these. If you’re using a truck bellhousing and transmission, you just grab that Magnum flywheel and you’re done. But for the A833 setup, it doesn’t appear to be a suitable solution - at least in my view.
I am saying that if you took a truck flywheel with a 143 tooth ringear then removed the ringear milled down that surface to the same diameter as the 130 tooth ringgear and then installed the 130 tooth ringear back on the now smaller diameter flywheel you would end up with a 130 tooth flywheel with a tonewheel. I actually had a machine shop do that for me. The tone wheel on my flywheel is actually a separate pressed on piece. I did forget that you would have to redrill the flywheel for a 10 1/2 inch clutch. After thinking about it there might be balance issues but I'm not sure. I think your method was awesome and I was just shooting out some ideas. I am a new subscriber and really enjoy the channel along with your humor. @@DeadDodgeGarage
@@moparfan4388 yep - I understood the suggestion. Re-drilling the flywheel for the small clutch would indeed solve that problem - but that’s not something I can do quickly and free-ly by borrowing a brake lathe. Honestly, just the amount of machining involved in my method is probably enough to throw off the balance. I don’t have any resources to deal with balancing parts like that. Some day, I’d like to figure that out… Appreciated! Thanks for being here!
Yeah it's amazing that no one offers a ready to go flywheel for the factory injection and a manual trans . What I may try is getting a new 5.9 flywheel already drilled for a 10.5 clutch and doing exactly what you did with milling down the back where you did but just enough to put a tone ring on with an interference fit. I am going to start trying to find another flywheel from Pick and Pull with a removable tone wheel $50 out the door. You can use a magnum flex plate to clock the windows in the correct orientation on the 10.5 clutch flywheel. There has to be a simple fix but without rebalancing and drilling for the 10.5 clutch and I believe what you did with the flexplate is the key. Well thanks for the input and if I come up with something I will pass any info along . I really enjoy the channel and will start mentioning it to my mopar buddies. Cheers.@@DeadDodgeGarage
Cool
130 tooth 10 1.2 inch clutch 143 tooh 11 inch
Right. That.
Hello! I'm doing this 3 pedal conversion on my 67 as well, this video series was very helpful. Did you ever get to adjust the pistol grip to keep it from hitting the dash?
It was weird - after driving it a bit it didn’t seem to travel that far anymore. Don’t know what I did wrong with the shifter setup, but it was clearly something. Haha.
Did you order a specific pistol grip shifter, or one for a 68 charger?
What if your not running crank sensor will the same manual fly wheel work or does it need weights welded to it
It needs to be weighted specifically for the 5.9 Magnum. It turns out there is a flywheel commercially available for that purpose - but I don’t know who sells it. You can also do the same trick with sandwiching the flex plate just to get the weight. We have done that.
@@DeadDodgeGarage mines carburetored could I cut the tone ring off were I can mount it flush behind the flywheel so I wouldn't b cutting anything off the flywheel just the tone ring off flex plate think that would be alright
@@briantate401 In theory, absolutely - but in practice I would want a machinist to do this, as cutting by hand could well throw off the balance and ruin the party. Also, I think the weight is pretty close to the outside, so you may have to cut it right at that edge. In my view it makes more sense to just machine the flywheel at that point - easier to do reliably, and you've got the future option of EFI, which I have found is easy to make work and really good.
I want big boy chips
Hey man would you suggest this process with np435
With NP435 I think you can use a 90s Ram truck flywheel? You would need to verify the diameter and flywheel tooth count, but I am pretty sure that is an option. I haven’t done this on a truck flywheel so I don’t know if the construction and dimensions are similar enough off the top of my head. But there is definitely a way to do it.
