Help! ZO6 hp upgrade

[stush]

I am looking to upgrade my 2006 ZO6 to 600HP Should I use Katech or Lingenfelter

I don't think you could go wrong with either, so let your wallet be your guide.

My vote would be Katech. They have a lot of experience with the LS7.

Getting to 600hp shouldn't be too complicated.

I've been investigating the same. I looked at Mallett, Lingenfelter and Katech.

I am leaning towards the 630 or 660 package from Lingenfelter. Mostly because they provide a 3/36 warranty and package costs include labor. I have also heard great things from people in the area having upgrades through Lingy.

Either way you go... big smiles to come!
