Hey Josh, I was just in Atascadero this weekend picking up an LS1. I used to live down there for a long time. I'll be back a couple more times this month and next.

Also.. something to think about: The aftermarket cams will need periodic review of the valve springs if you go over a certain lift. The 525 has some sacrifices in order to achieve a higher HP number, but it's under warranty, and theoretically won't need valve springs to be changed.

Texas Speed has a cam that adds 104 HP to an otherwise factory LS3, but it's going to be rough on valve springs (which might not be ideal for a daily driver car) and requires tuning.

The headers and intakes most people put on the engines also helps a bit with power output. Tuning makes the most of these also.
