I'm about to put some new pistons in a 3 cyl Ford 4000. Interference, valves and head on these engines. Test fit of the pistons shows them to raise a little higher above the block than I feel comfortable with. Machine shop can shorten my rods about 10 thou for about $65 apiece. I could cut 10 thou off the tops of my pistons in a lathe for free. Adviseable? Or not? I know racing engines have pretty close tolerance on piston and rod weights. How close are run of the mill, out of the box tactor pistons weightwise to one another? How about rods? Normally I would throw these in and not give weight a second thought. But cutting them makes me wonder. Could I make a difference in balance? 3 cyl engine aint the smoothest to begin with. Maybe go locate my local drug dealer and ask to borrow his gram scale to weigh my pistons? I could do a little fileing and weighing if it would do me any good. Make it smoother. Maybe this is rediculous stuff to even think about on a 2200 rpm tractor. But I want to know just the same. And this is a good place to ask. Thanks to any and all.
