Where can I find a sleeve for a 426 piston?

Any help is greatly appreciated as always.....thanks in advance...

isn't that just a stock sleeve bored 120 over?

 

I heard it needs a sleeve. If it is just a stock sleeve bored, then someone please confirm it.

 

Just a stock sleeve bored. I'm nearly 100% positive the size is 89mm- It's been about three years since I did mine. But for sure, it is the stock sleeve.

I think the 416 is an 87mm the 426 is 88mm and the 440 is 89mm [img]i/expressions/face-icon-small-wink.gif[/img]

 

I know you can build a 420 too. I think it is 87.5mm. Thanks Sicko [img]i/expressions/face-icon-small-wink.gif[/img]

I'm not bashing just asking [img]i/expressions/face-icon-small-wink.gif[/img] why would you put a fresh sleeve in and bore it to a 426? the only way I would go to a 426 is in a last ditch effort to save an old cylinder. with the 426 you end up with really thin walls and no room to overbore. what I'm saying is if you put a new sleeve in and bore it to a 426 on your next rebuild you would have to put a new sleeve in again. seems like a waste for so little power gains.

 

the stock sleeve can be bored up to a 426 (88mm). after that, you need a new sleeve. however, many people recommend getting a new sleeve when running the 426 because the stock one does get thin with the boring. you can get sleeves that fit 426's to 440's. i would contact C&D racing. the # is 308-696-7805.
