I have changed my plans. Instead of using a LQ4 block and building that i have decided to just build a LS3. It will be eaisier to get the power and reliebility I am looking for. So I have started saving for the parts and started researchiing and picking out what i will need. I am looking at what I will need for the PCV system. Does the LS3 valley cover come stock with the PCV provision and would a catch can be the best way to go so oil isnt being drawn in to the throttle?
