Lewis: Go with the block part number, 130 should be 366204 R1, and unless someone has modified the block, you shouldn't have a problem. It should be 3-1/8" bore, however someone may have bored it for 3-1/4" sleeves. Then you have the genius who may have bored it for sleeves from block part 354898 R1, R2 or R3. Don't laugh, I've actually seen that recommended here at YT. 354898 block was used in SA after 310300, all SC, 100 and 200 tractors, the actual block is bored larger than 366204 block, thus all those sleeves are actually thicker than 130 sleeves. 140 also uses thiner sleeves, however that block part number is different again, 367825 R1, R2 or R3. Years ago I would have said stick right with CaseIH for engine kits, and I may still be right. I suspect their parts for these old Farmalls are just as much aftermarket as all the rest by now. I probably had 15 to 20 engine rebuilds on Farmalls done lifetime, all of them farmed out to outside shops. The failures used aftermarket kits in all cases. In all cases where genuine IH parts were used, the rebuilds lasted equally as well as the original engine. I would never shop for an engine kit on price alone. In fact if I were shopping for a kit for my SA, 130 or 140, right today, I'd go right to CaseIH. Don't listen to me though, as I haven't had a tractor engine rebuilt in 15 years, long time in this business.
