Its says in your sig that you've already got a 410...

I would get a TC or Sparks Motor. TC is really good with the 300 Motors and so is Sparks. I have a old magazine where they both built 300ex motors into 400`s.

Sparks and TC are both great.
I'd go for a 330 kit if I were you. The 400+cc 300ex motors are very unreliable and must be rebuilt every year atleast.
But If you want power, why did you buy a 300ex in the first place?

id say pro fab would be a good choice i have heard they build a killer 300 motor. they also bulilt the houser crf450 quad on the front of atv sport so id say they are pretty reputable.
