I've been doing some looking cuz one of these days I'm going to have to overhaul my U. For some reason I don't understand standard pistons are readily available but oversized ones seem to be rather difficult to obtain. 427 Chevy tall block pistons look like they stand a chance of working. Everyone please keep in mind this is hypothetical at the moment I'm trying to do research. I know the wrist pin is a different diameter but does anybody know what the height of a M&M 283 piston is from center of pin to the top of the piston? Or is anyone ever tried to do this before?
 
Standard pistons can be found everywhere because as the engine cylinders wear and it is time for the over haul. No re call for standard pistons any more unless your in a pinch. You have to bore the cylinders oversized to like .20 over what ever you are not going to use standard pistons in that!? NO of course not so they only way to you can is to bore it then sleeve it back to standard and that adds to the cost. Check with this guy Charlie I think he had oversized pistons made. http://www.external_link.com/
 
Go to the Minneapolis Moline website and find Wendell Everett or Stamm tractor parts for oversized pistons, they have them and are more common than you think.
 
You speak as if these pistons are new old stock. The stuff that I'm looking at was made within the last year. And they still only offer standard bore I understand the physics of engine wear. I just don't particularly understand why a company that was making pistons for one of those Tractor today would only offer standard bore
 
I am pretty sure you can buy new oversized pistons from several sources. I have a nice used set of .040 over if you can't turn anything up.
 
Yes you can get new oversized pistons up to .125 over but they're not cheap, somewhere around $225 per hole. Just have to know where to look.
