Vortech or Stillen

Keep in mind that I know very little about this topic, but from what I have read on this forum, the Stillen puts out more HP in the low RPM range than the Vortec. However, the Vortec has the higher HP rating at higher RPMs. I know that the Stillen requires a new hood or modding it to accept their SC.

Perhaps this will be of some help.

AAnyways, the vortech also needs serious tuning.
While the Stillen needs a new hood (looks damn sexy to me tho..)
Dont make your descision on us few, do a few searches and find out.

It seems most people here with the vortech are quite happy with it, some have not even done any tuning to it.
