I'm going to say no and that's based off my own personal experience. I didn't want to buy their fancy glorified Holley so I used a regular 600cfm with vacuum secondaries. The engine wouldn't create the vacuum needed to open the secondaries and that fuel circuit wouldn't work even if you manually opened the secondaries. I called RB for help and because their fancy overpriced glorified Holley is specially built and proprietary, they will not give any information on it. All I got from them is that the base plate is completely different, some ports are opened, and some ports are closed? The jets are also smaller in the RB version as compared to what typically comes in an off-the-shelf Holley.
