I got a 351M with a stock 2bbl carb on it, I've been looking at putting a Holley 4bbl on it, from the looks of it-the front two ports on the 4bbl are actually smaller than the 2bbl ports, and I've been told that the back two ports(which are bigger) only open up when you really get into the throttle, so wouldn't that mean that at normal hiway driving the 4bbl would get better gas milage than the 2bbl?
