tecnical question about Intake manifold, Pic Inside holley intake users come inside!! Isn't there supposed to be a hole on the left side of the TB opening aswell?
I thought there was supposed to be an oblong hole on the left along with the regular hole on the right. I just got it today and wasn't sure if I should drill one or not.

The OE hole on the LS1/6 GM intake feeds crankcase vapors (or, it is suppoose to only do that and not oil) in front of the throttle body blade. This design (Holley intake) pulls in the vapors from behind the throttle body blade, from what it looks like. You will still get the PCV effect, it is just operating differently.
