Hey guys I need a few ideas on pistons.First off it's a 560 with a 3 3/4 bore 291 and I would like to find a set of dome pistons for it.The ones that are in it now are IH pistons with a small dome and a dish on the side opposite of the dome,,is there something out there better?Second of all can you buy just the piston some where,,,my sleeves are in good shape and show no signs of wear.I can't see sleeveing it if it don't need it.Any thoughts? Eric BY the way I got a really good fasthitch off this tractor I would almost give away,,, if anyones interested e-mail me at farmallpuller@peoplepc.com

560puller, you have pretty good potential engine now. If the IH 706, came out in an LP version, and then add high altitiude to the order if available. I know the 806 lp high alt pistons are next to impossibile to find new. 706lp? maybe,, Im not sure, the 806 LP high altitiudes are next to impossible to find. I use these style pistons in my farmall H pulling engines, and I think I got the last set around here. Look for high altitude pistons, LP pistons, or High alt LP pistons. Only other option would be to change the head, and go to flat top pistons, but, that style set up would make more HP VS the high alt Lp piston set. You may want to start thinking about how to feed this engine fuel. you will have to do some carb, governor, and distributor work to really get it right. Its easy, and Id be happy to help ya out. I built a 460 puller last winter, its a bit different than most 460's out there, but the engine is the same, just got done building the carb distributor, and the governor on it, and that made a different tractor out of it. Mine is a C-263, out of a combine, its getting a new high power cyl head and pistons this year, have some good info to share! Hope this helps,, left the email open. ChadS

I'm doing sleeves & pistons on my old Super A. I wondered about high compression, step top pistons for it. I decided to go with something more like stock, because I don't necessarily need any more HP for what I do with it, and I thought the higher HP might over stress the clutch or something further back. Also I got to wondering if my starter could handle more compression, It cranks slow enough as it is.

is the engine in the tractor an actual C291 or a C263 with the conversion sleeve set to C291?
