Looking at some oversize pistons to put in my 1944 John Deere model A. The tractor had .045 over cast pistons in it as well as the later A4648R rods when I got it and I was thinking of having it bored for .090 high compression pistons. I'm scratching my head though because most places only show std. size pistons for my serial number? (547xxx) Most have them for 584001 and up. One or two places have them .090 over for my serial number range but they are more expensive than the others. What is the difference between the two? Is there any issue using the later pistons?
The plan is to have a later gas head put on when it goes back together in place of the all fuel one. It already had a 71 carb and gas manifold as well as distributor ignition when I bought it.
