The hotcams website lists the same part numbers for both the 400 and 426, so yes, it will work. The site recommends that the cams be used with big bore 400s or 426's, but when I put mine in I spoke with hotcams and asked them "Why?" (ust currious as I have a 426...) They said yu get a bit more performance boost with the 426, that's all.

As far a what you can expect, if your 400 is "YZ" timed, you can expect a bit more bottom, a huge midrange boost, and a bit more overrev. If your bike is "WR" timed (stock), it will feel like a completely different bike

No...the intake cam gives the peformance boost. The exhaust cam is very similar to the stock YZ cam. You do ge tautodecompression, though, which is well worth the price of admission.

You can install just the intake. You get the auto decompression with the ex. cam so it's a worthy upgrade to toss in there too. You could always just do the intake for now and add the ex. later. I just put both in mine and wish I had done it sooner.
