I did exactly this ... wanted to make 500whp.
Upgraded the Vortech Impeller to SI trim and used the Stillen 9 lb pulley ...
It produced 483 whp/ 378 tqe at 11.9 psi.
Grenaded the stock motor as a result, and now I am having to rebuild it.
(Should have built the motor in the first place, it would have saved me time, money, and grief).
Can't say for sure if your stock motor will hold up, but I definitely wouldn't do both the impeller and pulley at the same time...
