It appears I have room for a 518 in my 65 D100 slant six 3 speed pickup.?

BTW This is twin to my D100 at ebay. For great pictures check this out! 300261515094 It is mine to sell. Nearly a twin.

What problems will I face insofar as bolting up to slant 225? I am not as concerned about the drive line or rear mount. I am not concerned about making the lockup work. Not concerned about linkage.

My biggest concern is the mating up of tranny/tourque converter to the block and starter.
Has any slant sixer done this.?? You guys have done everything else. LOL

I did see a similar topic briefly mentioning an A-727.

My 518 came out of a 91 one ton van with a 360. A lot of floor clearance in this recipient D100. I would even make more floor room if I had to. The D100 presently has low rear gears so the OD lockup should be just perfect if it will marry. gl/6

that 1 ton van trans may not even have lockup; I put one out of a 92 (last year for a NON Magnum 360) into my 88 D 100 some years back, and it didnt; Mopar Perf used to sell one under their P-parts program (nothing "special" about it, pluched right off the assembly line) that also did not have l/u.

You'll need a \6-to-V8 bellhousing adaptor and crankshaft spacer. Such an arrangement was used in pre-1969 (and a few post-1969) slant-6 trucks and vans equipped with 727 rather than 904 transmissions, and AREngineering were making a nice aluminum setup a couple years ago, but quit due to lack of demand. So the parts are out there, but you'll need to beat the bushes to find them. Some crossmemember modifications may also be needed, and you'll have to put together a control system for the overdrive. Ummmmm...somebody out there on the internet figured out how to do that, lemme see if I can dig it up...

*keyclick noises*

Got it! Here's the tech page I had in mind.

Easy to do.

Cut out the crossmember. Create a new crossmember for the tailhousing mount. Attach the usual cables and whatever shifter you want.

Between my 833OD and now used 727 I got one of AndyF's adapters (see on this forum) and mated it all up on my bench test chassis. Then I mocked up the 727 and decided to go with the 727 because a 518 shifter deal fell through for me and I wanted to get on the road one certain weekend and had a Hurst Promatic 2.

I still have a custom made driveshaft and Andy's adapter, new in box, if you are interested in either. BTW, the 727 is all I could have hoped for. You turn about 3,000 rpm at 70 compared to 2400 with the 833, but I don't do long road trips anymore...I went for low end kick and the 727 sure has it.

One thing to note is they changed the style of switching the O/D from the 1993 model year on, the pre-93 have wires you can hook up to a switch on the dash (like the Trucks), and switch it on and off if needed)

DI, you sure the changeover year wasn't '95? See the page I linked above.

what year did they swap from the 42/46RH's to the 42/46RE model?

The RE's are shifted electroncially and the RH's are hydraulically governed... I thought this swap was something close to:

1989-1991 A-500/A-518
1992 Designated 42/46 RH
1993-1994 42/46RE

Rock, I have not used the Quote before so hope this posting comes out OK.

Rock, because you have a D100, and you already having a 727 in a D100, I will pursue this post , hoping (quote?) it reaches others as well.
I will soon re-read those ealier other posts which also have excellent info.

You have a 727,.. Mine is a 518, bigger in girth and longer than your 727. Do you think it also will clear everything?

I will of course be making a new crossmember.

Drive shaft you have would not suffice due to 518's longer length and it is the short box.?

I need to look at adapter you have as to get on same page as discussed adapter item.

Comment: I should be about 2650 rpm when in lockup at 70 mph. With my present 3 speed at 70 I am revving much too high. Besides with slant six tourque,this lockup should do nicely. eh?

PS. For info,.. It is a dash switch lockup.

Hey guys, Considering I don't mind fabbing, is the 518 lockup type automatic a good choice for a 225 ? (Strength of 518 is not my hangup.)
BTW it's a short box truck. A near twin to the one at ebay in top post.

BTW, For Pictures the twin to my 518 mod is ebay at 300261515094 in the ebay search box.

I cant imagine this is a tough swap. You may need the 4 speed floor hump for some extra space. I would try to get the 518 cross member as it will likely be easy to adapt to your chassis.

Rocks driveshaft may have the yokes you need......

Would I do a 518 swap? .....sure ....except Im a 5 speed kinda guy

Yeah....Im the one who destroyed this rare, vintage automobile.....

Sandy thanks for the hump and yoke tip.

I was also a stick driver till my 72nd birthday. I think maybe torque and comfort and a 518 for now. I am also going to add A.C. and P.S. and get rid of that dang 8 track. After some amps then maybe more cubes and compression soon after.
Like 540 cubes and 13 to one. Then I hafta get me a five speed.

Too many mopars,-Not enough time. (I just replaced a couple words)

Hello,

I was a gear banger til I hurt my knee...and darn if I don't love an auto with a ratchet shifter or a quarter stick even more. glad you are with the forum.

First, as to adapter, use the search for AndyF and you will see the beautiful piece...CNC made and anodized. As I say, mine is new and I would let it go fairly to another trucker.

Then, when I mentioned my bench test, I have a complete chassis with no engine and body for fabbing mockups. I put on a block of what I need and a tranny I am going to use. It is one heck of a lot easier to fab standing upright inside a frame than lying underneath. that is why I told you it will fit.I added a clever (I think) little clevis device to convert to rear wheel parking brakes from the A745 three speed driveshaft brake and there is plenty of room to workon top of my 727 up there, and there was with a 518 case.

Next, the 518 is three inches longer than a 727 which is same as an 833 ong tail. Now, my driveshafts were made for a 3.91 positraction in a 489 case on a shortbed d100. I wanted strength so used big slip yoke on tranny end for , what is it, 8290 U joints...the big ones. My 3.02 pinion came with thelarge u joint yoke. If you need to know how to measure a driveshaft length, there is as thread here.

Yeh, you could modify a 518 crossmember but it just seemed I could never find one when I was looking. I made mine out of 3 inch wide channel iron. Amazingly the tranny mount bolted directly on. Oh, befgore you take what you have apart, cut a piece of plywood to fit between your truck bed and driveshaft slope so you can duplicate the pinion angle. Being shorter didn't really change the slope, but I went to a truck driveline shop anyway and had them check my installed pinion to drive angle.
