Question about GM 5.3 Engine - The 1947 - Present Chevrolet & GMC Truck Message Board Network

**Already Gone** · 10-14-2008, 10:33 AM

For the last 2 years I've been hunting all over the net and locally for a Suburban that would suit me. Anyway I found one locally the other day that should work for me but I need some advice. The one I found is a 2000 with the 5.3 engine and I guess a 4L80E Trans. I do not know anything about the 5.3 GM engines and I know a lot of you folks have daily drivers with that engine in it. My question is is the 5.3 as good an engine as the old 5.7 TBI and 5.7 Vortec engines? Does anyone have a 5.3 they have put 150 to 200,000 miles on cause I'd like to know how its standing up. Thanks...
