Flat Pistons Vs. Dome

I am about to start putting my C113 engine back together. The local machine shop ordered the new sleaves, piston etc, and today he told me that the pistons have a dome top. Now I've heard of dome pistons before, and I know that they increase compression and therefore horsepower; but that's not really that important to me. My question is, is there any down side to these pistons ? Should I send them back. My concern is that the additional power is going to be stressing the other parts of the engine or tractor. The original pistons were flat.

Thanks all.

I remember someone on this board saying that they had overhauled I think a couple of Ms and had put the standard bore flat top pistons in one and overbore step heads in the other one and said he would never put the standard stuff in again.

These tractors were built heavy enough to handle at least twice as much power as the engines originally put out. They were designed to run on around 75 octane fuel also, today the cheap stuff is 87. I know I would never put flat tops in anything I was rebuilding.

Brian, I am restoring my "POP,S" Farmall C (with alot of good guys on this board helping me). My father has run domned pistons for over fourty years and this is when the tractor worked all day, hard. It was overhauled once when he retired from farming and kept the tractor (it was the first tractor he owned and would not part with it thankfully). Now-I have took the engine down just to check before restoration and the engine is fine. It creates roughly 5 HP on the Farmall C and it in no way is bad on the engine. The way in which you drive and run the engine is far greater than your domned pistons. This a voice of experience. Good luck with your Farmall. Boochie

Brian: There is a lot more stress when a person snaps out the clutch or hits a stone when plowing etc rather than adding 10percent more engine. G

It is almost rare that a fella would put flat tops back in after a rebuild. I would guess that the MAJORITY of the farmalls either have oversize sleeves and or stepped/domed head pistons. Won't hurt the engine a bit.

You shouldn't have to send them back....it won't be that much of a difference in a 113...won't hurt your engine a bit. Most engines that were overhauled at one time or another either were overbored, had dome pistons put in, or both....bolt 'er together, it will run like a sewing machine.
