I also had a 69 Camaro with the off road cam and headers and a factory crossram set up. You need to seriously consider how you are going to drive the vehicle prior to adding the intake. You are going to be flooding that engine, not that that is a bad thing, and yes that is what it was intended for. However taking off from a stop especially when the engine is cold, can be difficult to say the least. Originally these cars had no choke plates, so proper warm up is required before they will function well. I say this as after I installed the crossram on my car, I ended up driving it less. It is a nice set up for racing, difficult for street, especially low rpm. Best of luck with your choice.
