Allis 301

Any thing is possible with enough time and money. But no to your question. 262 plate don't have square groves for sealing around frank and cam, plus bolt holes are different.
Guess you want to put 301 in D19 or D17?
Best would be to put 190 torque tube on D series or make adapter plate or redrill 301 plate to fit D series, then don't think 301 flywheel will fit into D series bell housing.          MACK

Yes, but is only 10" clutch.     MACK

Use the 301 backer plate and flywheel, it will bolt up to d19/d17 bellhousing. If using d17 gas, the input shaft is a different length then the diesel. The 301 flywheel and clutch will fit in as well, but will require some grinding in rear of bellhousing. if my memory is right you have to grind some in the starter pocket as well to clear nose of 301 starter.

Looking for some more options, the Buda engine became allis chalmers then white/allis and then agco, so would the allis 301 fit into some White tractor or possible cockshutt 40 or 50 ?

a 433 (200 cu) engine from an F2 or 6060? 6070/80 should bolt up just like the 301 without the length issues.  same engine minus 2 cylinders

You haven't told us what you are trying to do. Makes it hard to give the best advice when we are in the dark as to what your goal actually is.

Quite a few things are different on the two motors.  The steering rod from a D19 won't clear the 301 motor.  The radiator ports are in different locations.  The throttle shaft is different.  Things like the tach drive are on the other side of the motor which means that they spin the other way.  You really need to park a 301 next to a 262 and start looking and measuring.  It can be done, but its not one of those projects where you just unbolt this unit and bolt in the other unit.  It takes quite a bit of modification so its just not practical.  Anybody with the skill to do it is better off doing something else with their time.

It can be done. I've seen a 301 in a D17. A friend has a 301 in a WD-45 puller and his Dad just put a 301 in a D19. 

What would need to be done to a A-C D19/262 engine to get to 100+ hp ?

D-19 gasoline tractor when tested at Nebraska Test in April of 1962, the maximum PTO HP measured was 72.63 HP.   There's really nothing you can do to change that. It was  finely tuned as well as the Engineers could tune it. If you swapped out the factory carburetor for the one from an early model "F" Gleaner or late model "C-2", you would gain 10 HP.  I imagine a carb from a 190XT gas might be a little bigger yet and I'm sure there are larger carbs than that. Other than raising compression, increasing bore and or stroke and changing camshafts, valve sizes, etc there isn't anything you can really do but install a larger carb and increase RPM's.

Stroke is almost out of the question with out a lot smaller rod. Cam is notched now for rods to clear.
Bore is almost impossible, because you get into head bolts. I bored a block out to a few thousands of head bolts. It held until pump belt rolled over. That is when it took the front of block out.     MACK

Did that cause any head gasket problems or would a 1/2 in. stroker crank be more reliable to get the same hp ?

What was the compression on that, was that with stock head ?

My cranking compression pressure was 300-320 psi if I remember right.....this was many years ago. Had to use 114 octane racing fuel.  I used the thicker diesel head gasket to get the compression down to that figure with a stock gasoline cylinder head.

That engine I built ran us for 6 or 7 yrs and then we sold it to someone in Minnesota and as far as I know it is still running in a puller.
