I bought my 82 K10 4x4 that has a stock 454 in it about a year ago. I got it with no intentions of it being a daily driver but it has turned out to be one

. I'm thinking about down sizing to a stock 350 becouse I'm only getting around 9.5 MPG with the 454. How much of a increase in fuel economy would I get by doing this? I would think it would be getting around 13-14 MPG with a 350. What are your thoughts? Not sure if I should have posted this in the engine forum or not.
