I would call some of the more well known shops such as Vengeance, FSP, PCM, Jennety, Lethal or Rhino on here and discuss your goals with them. They are the experts, use there knowledge to your advantage. Nothing wrong with soliciting opinions on here, but your going to find that most will recommend what they already have. Also, you might want to consider a custom grind. A custom gring in most cases will be the same or just slightly more than an off the shelf grind. BTW, do you have an LS3 or L99 engine?
