Aces, I have been looking at the 6 cyl engine components to make a few more HP, and try to keep the parts all IH. From what I read, the pistons have a different compression hieght between the 460-560 engines. Lately, I am not into big cubic inch to make power, just redesign the pistons. Anyways, I am wondering if I could use the taller piston of the 2, (460) I think is the taller one, and put it on the 560 rod, and push the piston up in to the head more to make compression higher. I can machine them to clear the head, I am working on this method to do this to my 460 puller with the 263 combine engine. 3-9/16 bore. Wouldn't it be cool to see a 100 hp 263 with a stock bore and stroke? and on pump gas. It may not be the biggest HP gain in the world, but hey it is possible, lol. I know you are an IH buff, so am I LOL, did you used to work on them all the time? ChadS

If I understand correctly....changing piston and rod will not affect compression. You will effectively move the "swept" cylinder area, but pull in, and compress the same volume. To get more volume, and greater compression, you would have to change the crank throws. Crankshaft throws will determine engine stroke. Doing what you mention would not change stroke or compression.
Maybe I misunderstood your whole statement...wouldn't be the first time....Stan

Stan you are right Stroke gives Cubes and adds to the compression ratio. If one adds one inch to a 3 inch now you one more inch compressed into the same as the 3 was.
Chad the combines mostly had sleveless blocks

Chad. After thinking about this a little more the rings are to close to the top of the piston to machine the difference is below the rings and then I don't you have much clearence between the flat part of piston and head.

Chad. I worked for 2 IH dealers back in the 60's and 70's for a living that is, and to work on some JD's at the first place because the shop manager was an old JD man, that's why I love the IH I sould over haul an H or M and have it running and read to go before he could get and A or B JD apart and the rear ends on them don't want any part of them. Now that you know that about your question. I don't think your are on the right track here. This is why I say that. The difference between the 460 and 560 gas or desiel is stroke. So what they did to do this is the rist pin on the 560 is just below the oil ring maybe 1/8" where the rist pin on the 460 is maybe 1/2" below the oil ring that keeps the compression ratio close to the same. The rods are the same part number, so all i did with the 460 to make them come alive was put the 560 crank and pistons in the 460 block and I could get same horse as 560. and with so more RPM's I could get in the high 60's for HP on either. If I put on 706 exhaust manifold on the 560 I could get 70 out of 560 gas most always got over 70 with 560 desiel with about 2100 RPM. Dd put many M$W turbo's on both 460, 560, and 706 with 282D had a 460 with 282D running 105 HP. Never did more with gas than exhaust manifold. So for your question I don't think you will gain, don't think you can take enough off top of piston to make up for location of rist pin when rods are the same.

Shockingly, when I was 16 I worked for a Case dealership for 2 years through ICE vocational program in school. Washing tractors, and service work. Then Case dealership sold out, and worked in a farm repair shop. It was alot of work, it was mostly installing grain drying equipment, bins, and those tall elevator conveyors, lots of welding, and cutting. It was great. The owners of the company I worked for, had a few drag racers, and they let me hang out and watch them tinker with ther cars. I built a drag car as well, I learned alot about carbs from those guys, I got my first tractor a 54 super H when I was 11, and then started going to pulls and well, lots of late night tinkering with the super H, a few years went by and I built a stroker for our 50 H, and then a year later built a bigger engine for our 40 H, I am proud of that little H, it sure has a big heart, and loves to pull. This 460H i put together, I have learned alot about the IH 6. they are a very powerful engine when fine tuned. The one I have is out of a 70 IH 403 combine. a 263. It has the high rpm single arm governor, I had to rebuilt the head, due to a burned valve. I noticed it was sleeveless as well. Is that common? It has aluminum cast pistons, and are high domed, they look like a firecrater, but seemed taller on piston dome. It has 165 psi of compression, I built up the carb and ignition, it is an honest 80 hp. I run 105 octane blended fuel in it, gulps it more like it, It took me a while to get it right, everything from my times messing with drag engines, and all the little HP tricks paid off. one sweet sounding engine. Chad
