    None. A V8 is the best for a full size truck.

    With the Chevy/GMC full sized trucks for those years probably the 5.3L V8. 18-19 mph highway, not too bad for a V8. V6 in a full size truck will be overworked.

    What are you using it for? Full size trucks use Full Size Engines. Remember if you size it right, those engine's don't work that hard. I have had the 5.3, 5.7 and now 6.0. Love them all for different reasons.

    I've had a couple. an 89 1500, and a 98 2500HD, with the 5.7 v8 in them and that was a great engine, but lacked a little in the torque department. I now have a 2002 with an 8.1 with the Allison transmission and it is a work horse. So it depends on what you want to do with it. I tow a large 5th wheel trailer, so, I needed low rpm torque, and wasn't too concerned about gas mileage, although the 8.1 get 14 mpg solo. For a near 6,000 lb truck, that's not too shabby.

    They say there's no substitute for cubic inches. With that said, you may want to give Sonny's 1005" GM Hemi a try... should be able to handle anything you throw at it. Of course, it would be prudent to have a rich uncle from Saudi Arabia on hand to keep the feed bag full of oats.:rofl::rofl::rofl:

    I need to change my answer. My brother in law has a 2008 sierra with the 5.3L and at 60000 miles it is burning oil. GM is aware of a problem with the AFM (Active Fuel Management system) that is contributing to this problem. The fix is a oil shield, valve cover gasket, and cleaning agent (per TSB). Years affected around 2008-2010.
