    Question 99-Chevy 2500-454-2wd....Questions

    I'm looking at Chevy 2500 Suburban -454-2wd..... Im wondering - with the 2 wheel drive , 4.10 rear end , and the more efficient Vortec 454/7.2 - What type of gas milage can I expect? towing & daily driving...
    I have a 97 GMC Suburban-350-4x4 , with 101,00miles. I tow a 1966 -24foot Airstream trailer. HEAVY! So Thats why I/m looking at the 454....

    I have the same truck with the same rear end but in 4 wheel drive. I don't know about 2 wheel drive but I get 10 MPG towing a 28 foot trailer or not towing. Always 10 MPG. I would think you might get 2 or 3 MPG better but that is just a guess. I don't have any chips, headers or anything else on my Suburban...straight stock.
