ok no one has even given me a straight answer my 400ex has a 426 big bore, stage 2 hotcam, new timing chain and tensioner. I want to do a 4mm stroker I heard you have to use a vertek stroker piston but I cant find one that will fit my 426 big bore only the 425. where can I get the piston and what if any grinding is needed to make this fit:sad
