i'm a IH man and been pulling with a bunch of deeres that my friends run. now i came across a 1466 for sale. i'm trying to build it for pulling in our new 466 class but want to be able to keep it legal in the farm class, and be able to do small feild work with it. mabe have 2 diff pumps one for pulling and one for feild. now i always did work on the older m's but don't know sh*# about the 400 series diesels. any advice would be helpful.

i would go with the 436,little shorter stroke and later if you want to go big cube the 466 crank is easier to get.
give Lee a call at midwest diesel injection in Ft Dodge Ia,he can do the pump work,lines and injectors and is fairly resonable on price.
as far as head work goes you can if you want but on a stock bore engine the IH head flows fairly well as is.
you could also check pulloff.com and midnight mistress and look at the classifieds there for some used parts,but be careful their are alot of pullers out there and not all of them are honest.
i would want to have the pump checked by someone before you purchase it,if they have a problem with sending it to a shop,you probably don"t want it.
if you start to push too hard you might need to upgrade the clutch to a steel flywheel and pressure plate,which i would suggest anyway,better safe than sorry.

It sound like you may be a little mechanically inclined . Most service manuals are pretty straight forward.There si always someone taht can steer you in the right direction dont be intimidated.

The difference is in the crank shaft.The 436 has a 5'' stroke the 466 has a 5.35'' stroke.They are a good engine to pull with from stock to highly modified.You could get by with one pump the model 100 pump can be made to deliver allot of cc of fuel and be set back for farm chores.Don't no how much power you want a stock 436 can make 290+ HP.Larger pump and turbo your in the 300+ or go grand national puller 3000 HP.

Hey now I am not aware of grinding on the delivery valve where is that at and how do I do it. I have a 10 with a 466 and I take the adjustment screw right out and I still get my butt kicked once in a while. With the 466 all turned up all the way It makes 311 h.p. How much more could I expect.

the valve is ground in the seat area its hard to explain in writing. another thing we did is slightly drill the inj. lines at the ends they were crimped a little and the timing is important. i think we took the stops out also e mail me and i will give you my #
