Every 5.3 I have come in contact with in any trans/rear combination got worse gas mileage than any stock 5.7 and none could pulll a trailer on the highway without an overdrive issue. Now most of the people I know that own them are pleased as a commuter vehicle but none have much good to say when hooking a trailer to it and I shouldnt have to buy a 6.0 to haul with and get 10MPG. Like i said.....why have two engines when the 5.7 did the job of both????? I guess its like, why offer a 283, 307 and a 350 all at the same time?

I have a few mods (see above) on my 5.3l and a heavy foot. I get 17 MPG on the highway and about 16 or so with mixed driving. Not bad considering what I have and how I drive it
