Question(440 vs. others)

I have a 2001 with accesories(nerfs,handlebars,etc..) and a White Bros. Slip On E-Series Exhaust. Its really awesome.Even when it was stock it had outrun some Raptors or stayed even with. But anyway, if i put a Wiseco 440Big Bore Kit in it would it beat a raptor even one with an exhaust,air filter, and jets? also how much does it increase the 400EX?

it might get close but i don't think it would beat it. my neighbor is getting a 440 bore kit. they're pretty fast.

If it is just a resleeve, it might make it go a lil faster, but a properly worked 416 can smoke a 440 resleeve.
