We're in the process of installing a 426 engine into our 190XT and we were wondering if anyone else has attempted to do this engine swap. Using off the shelf Allis parts to do this is obviously not going to happen without major modifications and we're prepaired to do whatever it takes to get this big block allis in the small chassie tractor. We would like to thank everyone in advance for there input and time.

DW, Our association pulls in northern part of Illinois. And were planning on pulling the 190XT with the 426 in a naturally aspirated open class specifically the 5000lbs and 7000lbs classes. You can contact us at Allispuller@aol.com

HMMM, Nice project!! Is the 426 ,and the 262, do they have a plate that bolts on to the back of the engine block? if so, then that would not be hard to adapt, I have not seen one up close to know, need to measure the distance from the very back of the block, to the edge of the starter ring, so that possibly a stock starter may be used,, the flywheel would have to match the 190 specs as far as dimentions is concerned, unless a steel one is made, and any clutch spline may be matched up to the 190. Sounds like a sweet ride if you get it together,, ChadS

ChadS, Thanks for the input we have done some measuring and figuring and it look as if we will need to find another way to start the engine. We can get the 426 to bolt to the bell housing of the 190xt but getting a starter on it is going to be another story. The width of the 426 over the stock 301 is quite abit. The 426 block is going to partially cover the starter hole in the 301 backing plate not to mention the area in the bellhousing casting for the starter nose to go in to. Modifing the backing plate isn't that big of a deal, debating weather or not to cut the bellhousing open to accept the starter is a primary consern especially with the power we are planning on making with the 426. Any other ideas would be appreciated and thanks for your time.

you could always go to a front mount starter.
they are spendy,but they will work.
we also have put combine starters on IH pullers in the past to get them away from the tranny and down on the side of the engine.
when you do this you have to cut a good inch out of the bell housing,and you lose a bolt hole in the process.

I don't remember how the mount is shaped on the bigger Allis engines... the easies way would be to just make the adapter plate bigger and mount the starter in the adapter plate.. that should give you some room to space the starter out if you need too... But you would have to go to a front mount starter.. (depending on where the adapter plate is in relation to the flywheel.) You might be able to use a Deere or a Cummins starter... Good Luck

Redman, Thanks for the information, we had been talking about finding away to start the 426 from the front and the front mount starter with a ring gear on the balancer would probably be the way to go instead of cutting the bellhousing. Would you know where we could get some information on them or who could set us up with one?? I've seen them for sale before on other websites but I can't say that I've ever seen a Allis setup they all have been IH setups. Any information will be greatly appreciated, Thanks

the one we put on is off a drag car,no ring gear just some dogs on the center of the balancer.
they run on 36V but they will spin it over,check the web for front drive starters.

If you are going to all the extent of this conversion, could a flywheel be made to make it work? steel, or a remachined flywheel? I know I am mixing apples and oranges here, on my 460H, the flyhweel had alot of the same measurements from the 4cyl, to the 6 cyl. Just had to machine the flywheel to put on a different starter ring. And I got the stock H starter to turn the 6 cyl over like it was made for it. Maybe look around for any and all part numbers offered on the 426,, there may be one out there somewhere that may work with a bit of machine work. (flywheel) This kinda like stuffing a 460-560IH with a red diamond 501. Did the 190, have a plate that bolts to the back of the block, or is it all casted to the transmission bell housing with no plate at all? Could one be made? ChadS

ChadS, The 190 does have a backing plate on the back of the engine that the rear seal goes in and the starter bolts to or thru and then the plate bolts to the bell housing. According to our associations rules we have to use the OEM backing plate for the make and model of the tractor, so in this case we have to use the stock 301 backing plate on the 426. But the rules DON'T say anything about modifying the backing plate, so we are drilling and welding one up as we speak. Thanks to Redman we have decide to put the starter on the front of the engine and a ring gear on the custom balancer we have. Our rules also say we have to run a steel flywheel, no cast, so what were going to do is get a blank steel flywheel from one of the manufactures and have it drilled to fit the crank and it will be the right diameter to fit in the bell housing also. Thanks Katie

I wish you guys the best of luck!! Just about 13 miles south of me, there is a fellow who pulls a 180 in the ATPA. "The Smoker" twin chargers on the ol girl. They had alot of trouble holing the small block together, but they finally did, 200 psi of boost in this thing!!! Now, they are busting the input shafts in the tranny. Engine is holding stronger now, I have seen only 3 D-21 AC hook to the sled in my life and the ol 426 turned on like a "Pumpkin Gone Mad"!! LOL ChadS

Redman, Ahh now that's another great idea! Thanks for your help on the starter situation, now I think we need to do some shopping to see which is more installation friendly on our setup. Thanks again for your time.

Go to the Mid South pullers board and ask the Haneys from Alabama for help, they pull some very potent Allis Chalmers and also have a dealership.
