Hey I was just thinking about putting a cam kit into my Vortec V6. I was wondering what the best setup would be to go with on this and a ballpark figure on how much it would effect the performance? I don't have much experience in this field so any suggestions are helpful.

dude try this, summit carries hydraulic roller cams for the 4.3L vortech 90 degree v6, so look here first.
