If you want to lean that rascal out get you a big 2 barrel from a big block Pontiac and use an adapter and install it on your 350. It'll still have the power to pull, you just won't be opening up the big 4's. That where your gas mileage goes. That and my stepdad used to use a vacuum gauge to time the engine. Worked perfect.
