Ok 399cm but how do tell if it's a 400 bottom end. The guy I got it from said it was a 05 wr450f bottom end with a 400 top end. Are the even interchangeable?

don't think so - I know you can put the 426 barrel on the 400, but don't think the 450 stuff fits a 400/426 bottom end or vice versa

 

someone more knowledgeable will be along shortly
