The second ones are L92's they will fit but not with the stock intake. You cant use the L76 car intake either, not sure but I think you have to use the L92 truck intake. There is a site somewhere with the part # of the intake for That fits our trucks, I'll see if I can find it. Check over on LS1 Tech for a lot of good info on the L92's.
