Where did you come up with a 425 topend? I thought it was 396 with out crank work and 430 with. The biggest i've seen was a 452x and it wasn't very reliable.
I doubt you are gonna hang with a 460ex

four stroke teck has a 425/432/452 piston kits

A 350x can be built to pull 450s, a 400ex shouldn't be a problem...

You could always take it to a 452 and stroke it. But without heavy porting, not as much will be gained.

i can tell you that a properly built 460cc 350x will destroy a built 400ex

my buddy who has a 460 stroker big bore 350x motor in a custom 250x quad chassis also has a yz 426 bored to a 450 with cams and fully ported head, pipe carb,......all the goodys in a custom full race 250r chassis.

his old 250x/460cc quad will do everything the built 450 will do but easier....lol

so pretty much ill be able to keep up with the 450s not out run them.
