I used the Weiand 4032 kit on this tunnel ram:
If your manifold isn't drilled to mount the carbs sideways, there are adapters that bolt down using the existing forward mounting pattern that turn the carbs sideways. I used these adapters on the above manifold as it wasn't drilled to mount the carbs sideways. The manifold does need to be drilled for both the Holley and smaller Carter bolt patterns though. If yours isn't, it's an easy mod. I had to drill the smaller Carter pattern holes on this one.
