Re: carburation system
The flow of the "305 heads" is also killing your power. It might have bumped up the compression, but the gains are negated by the cruddy flow and small valves of the head itself. Match that with a cam that's waaaaayyyy to big and then you have to put your foot in it more to do anything. Therefore burning more gas in the process.
I agree that a Q-jet will do very well to improve fuel economy over aftermarket stuff. That was their job when they were bolted to these rigs at the factory. But just finding a dusty Q-jet on a shelf and bolting it on won't usually do the trick. You will need one built by a reputable source for optimum economy and performance.
