Does anyone know of a cast intake like this for a BBC? I have found a lot of them for LS but not BBC.

I think this is about as close as I found.

If you need two bungs, you are either out of luck, or you are going to have to weld in a second.
Another option is to either use a regular injection manifold or convert yours, and add an elbow to the top to get the throttle body forward.
I ended up having my sbc tunnel ram converted by adding the bungs and a fuel rail attachment point. Added two throttle bodies and a hat over them. In case you need to add some pressure.

Yea I have seen that one already, but am looking for something lower for hood clearance.
