Guest DeSoto Frank Posted December 26, 2009 Share Posted December 26, 2009 The tractor pistons may have a different "pin to crown height" for lower compression ratio; tractors were designed to run on low-grade fuels ( cheap!).... IIRC, CR on an N-model Ford tractor is around 4.5:1. Probably lower than the automotive version.Which engine are you trying to source pistons for ?

Guest knightman Posted December 26, 2009 Share Posted December 26, 2009 i was just wondering if they were the same as i have 6 good standard pistons for the 239 i recently redone some 8n and i remembered they had the same bore ,stroke and pin sizes thanks for your help i will measure the height of the pistons also i noticed the pistons from the v8 fit the sleeves for the 8n so i wll go from here thanks for the reply knightman Link to comment Share on other sites More sharing options...
Guest DeSoto Frank Posted December 26, 2009 Share Posted December 26, 2009 Don't know about the compatability; measure carefully before trying them out.If there's no clearance issues with the head, they will probably work; if they give a higher compression ratio, then your 8-N will have a little more power than stock.Shouldn't be an operating issue unless you're running distillate or kerosene in your tractors ! The N tractor engine was also available in the '40-'42 Ford truck, and is indeed basically one-half of a flathead V-8.I've also been told by old-timers that they used to use flathead Plymouth pistons in the Gravely model L walk-behinds...
