I have the opportunity to buy a IH 560 with a totally rebuilt gas engine. Might get it bought for $2500. Good wide front. No fast hitch. My intent would be to drop it into a good IH 706 with a scored piston or two. The engine in the 560 had the crank ground, head worked over, sleeves taken out and cylinders bored to the 301 cubic inch engine. Of course with new pistons and rings. I think the engine was done right including boiling it out, etc. My 706 engine has some piston slap so I think it is sort of on its way out. Didn't know how much part change over it would take to make it fit????? Does the timing gear cover stay?? Manifold?? Flywheel?? Clutch?? Thanks for the information.
