Hello Zoom This,
With an isolated runner type intake system such as used with the Weber 48IDA carbs, you need to run a single profile cam with around 110 degree lobe sepration. I have a 427 stroker small block with 48IDA's and I am running a Cam Techniques cam designed for an isolated runner system. I went with a complete roller cam and valvetrain which allowed me to run more lift but not sacrifice my idle quality and driveability. As for a lumpy idle, lets just say that when I'm at a stop light the car rocks side to side and sounds great. People pull along side and say "looks and sound great What the hell do you have under the hood !!"
Although there is absolutely nothing wrong with a single 4 barrel carb/single plane manifold induction system, they are capable of serious horsepower and generaly easier to tune and definitely easier on the wallet, I still can't get over how nice a Weber setup looks and how the Webers add a little more interest under the hood. People always seem to make a nice comment and walk away with a smile !! No right no wrong all fun.
