No argument there Tim, that just about any carburetor is better than the early and mid Rochester’s. But an engine is still basically just an air pump with a fixed volumetric efficiency. Your Carter-Weber is certainly a more dependable carburetor but that stock air pump is only going to pull in a fixed volume and the stoichiometric air/fuel mixture (approximately 14.7) remains the same.
Don’t mean to start a panic, panic, and I’m not about to argue the point, you are entitled to your opinion, just as I am, that’s what we’re all here for. The proof is in the pudding as they say. Dyno testing would be the only true way to prove the point. But if you could run your 235 up to 5,000rpm with a stock cam, springs and ports, your going to be shoveling up the pieces. If the engineers at GM calculated they could get more power simply from a larger throttle bore with the same VE then they certainly would have installed 300cfm Rochester “Bs”. After all, they did do a little bit of dyno testing on the Stovebolt over the years. Multiple carburetion most certainly benefits the engine when it’s been modified, but after all is said and done, we were talking about a stock 6cylinder engine here.
