Bottom line, NOTHING will improve on stock carburetion for fuel mileage. Nothing will improve on fuel mileage over a stock factory cam.
Well, that depends, right? You have to figure what the billion dollar engineering was pointed at. I'm not going to say that you can improve the Chevette's MPG, nor am I going to say that you can improve a Camaro's HP. I simply don't know enough about these things. I will say, though, that you could surely, if you know what you're doing, and have access to the proper parts, improve either the fuel mileage or the horsepower of any carbureted car. Clearly the engineers (or the accountants) made a compromise somewhere in the design. You either get more MPG or more HP. You could certainly tweak that balance. It's also conceivable that the engineers/accountants used cut-rate parts. We know they did on the brakes, and you could argue the same for the alternators. I've heard it said that the Holley/Weber carb was a cut-rate part, but I haven't seen any evidence that the Weber carb was any more than 2-5% better for HP, and never that it was any better for MPG.
In summation, it's not so much that it's a fully 'tarded idea that you could improve the Chevette. I'm not convinced your average Joe Blow could do so, but maybe somebody could. It's just that there's so much misinformation out there. You can't even learn anything, because 9/10 people will tell you bull$#!t. Add that to the fact that people tend to read "anecdote" as "data" and you're out of luck. What we really need is an accurate science-based website that debunks car myths. A snopes.com for engine repair. Trust me, I've looked online for answers to basic questions about how engines work, and there aren't any answers there.
