Looking at getting a 2002 GMC Sierra 1500 with a 4.8L V8 with 46000 miles. Looks Cherry but really would like the V8 5.3L. Do you think it would make any difference pulling a 6000 lb trailer. Thanks ...
3/4 ton, lol. Yes the 4.8 gives up power to the 5.3, but you're obviously after the best value and that's any truck that don't break down. You can run the 4.8 full throttle all day every day and You're not going to hurt it. One of the toughest small blocks made. stock long blocks hold up to a lot power. I wouldn't pass it up if it's the right truck.
