alright listen here my know it all buddy is telling me right this second that a 406, 416, or a 426 piston will fit in a stock 400 cylinder, someone please tell me hes an idiot.... if im the idot be nice haha

[ex_freestyle]

haha your buddy is wrong a over sized piston will not fit into the stock bore the only way you can fit a bigger piston is if you bore it out to the specifications only but the 426 kit will fit in the stock cylinder sleve then when you go bigger than that you have to get a new sleve

[xcracer416]

stock cylinder with a stock bore no they will not fit. you can use a stock cylinder bored to those numbers though. so yall are both right

[mike c s]

thank you so much now hes all rowled up, haha he bet his yfz that he was right, now i have a 426 and a yfz lol

if he specifically said stock cylinder then he would be right...
ps. i think 426 is 100 over? correct me if im wrong

[400sEXridr]
