Im also in the process of doing this, I picked up a kit that was designed for a SBC and im running an L92, it was all brand new and got everything complete for to cheap I felt. I hear the compression from a L92 is lower than a typical LS3, is this true? Useful information from a lot of smart guys on here. Who builds a nice set of Turbo Headers, I heard OBX from John 510 and Is there anyone in Oklahoma who can help set it up? I think I would like to finish the car and drive it before I blow the motor up but no problem in having the info advance and going ahead and placing the orders.
