drag race 400ex vs 300ex

what mods would it take on a 300ex to beat a 400ex in a drag race?

Alot of mods,,big bore kit, complete exhaust, cam, etc..and that's mainly to run with a stock 400ex.

Stroker motor!

You could bore it out a little out a pipe on it.diffrent sprocket size too.Then you could run with one in a drag race.
