I switched from a Big Gun to a DMC It is a bit better at top end. Get a web cam 450-451 grind directly from web cam. It is the largest cam you can get without changing springs and guides.
You wont believe the change. A larger carb would also help after.

99 426ex , Web Cam, FCR carb, CT revlimiter, DMC exhaust, XCT's ,K&N, One kit, Renthal 400EX bend bars

When using the Web Cam 450/451 grind cam do not forget to also change your rocker arms. There are hardwelded rockers also available at Web Cam. The hardened camshaft will wear the stock rockers faster.
