I run a crossram system on my vette with four side draft weber carbs , BUT it is an IR system . Some will look at a system like that and think that it is over carbed. The truth be known it is actually a bit on the smallish side . The ir system allows the tuner to [ too much time on his hands] actually tune each individual cylinders fuel aircharge. The result is an engine that is very responsive at any point in the rpm range .

The weber carb CFM range is easily changed and therefore can be made to provide the necessary fuel air charge velocity to give the engine a good ventuuri vacuum signal . Simply put , the gas and air will mix really good together when they should .

So as soo many others have pointed out to you ,,,engine system component selection is critical . There is a tendency when starting out in this hobby to go BIG [ don't ask me how I know ] and it is usually the wrong path to take . Good luck in your journey !
