Does a 426 piston require a new sleeve? I am rebuilding a buddy's 400 and he wants a 426 motor. I know wiseco offers a sleeve, but I don't know if it is required or if I can just bore the stock one out.
Thanks,

you don't have to resleeve it but is a good idea since that is the last bore in the stock cylinder and the cylinder walls are pretty thin and will create more heat but to answer your question you don't have to sleeve it.

My 2000 426 is just bore, but it is the last one before a sleeve is needed.

Nope. but I would recommend getting a sleeve to keep the heat down.

So in that case, does the cylinder get bored out to fit a thicker sleeve?Originally posted by Silverfox@C&DRacing

Yeah, its the regular 440 sleeve but its just 88mm on the inside instead of being bored out to 89mm.Originally posted by RIDER11X

Why would a thicker sleeve keep the heat down? It takes longer to dissipate heat through a thicker piece of metal than a thinner one.Originally posted by torqen2k1

Take it to a 416 instead.Originally posted by #77

your best bet would to get a sleeve. a buddy of mine has a 426 without a sleeve and he really gets some heat. headpipe will glow red and oil will bubble after 10 min of ridding.the dipstick gets so hot in the oil tank that its almost impossible to get it out with ur hands.so u should probably get the sleeve and leave those problems behind u.
man his quad is just messed up. that problem is WAY beyond anything a thicker sleeve would help.Originally posted by Tackett

I have a 463 stroker with a 426 bore on the stock sleeve and never have any kind of issues with heat!
