GM 5.3 Liter engine

[EDT]

I am looking at getting a GM rig with a 5.3 liter engine, I have never had a vehicle with this engine, but I have heard great things about it.  Any experienced opinions out there about this engine, and any problems with it?

Been very happy with mine. Strong runner and very dependable. Only issue i've had is a head gasket went south along with an injector. Sitting 120k now I expect to hit 200k. The 5.3 is the old reliable 327.

I have two. One with 120k noisy lifters at cold start up. The other 136k and is absolutely bomb proof. I love them both.

The 5.3 and its big brother 6.0 are one of the biggest go to motors for swaps in all sorts of applications, bombproof setup factory, and huge power can be made cheap. Om considering putting a 5.3 into my 90 suburban this summer. Smooth dependable motors.

I have a 03' Yukon XL with the 5.3  I toad a car home from Yellowstone and found it a little under powered, but then again, I'm running 35's on it.  All and all I am very happy with the motor, it has about 150k on it now.

What kind of gas mileage do you guys get on it.  Im thinking the EPA 13/18 will probably be pretty accurate.

I get about 13 with the 35's

The 5.3 has about zero in common with the old 327.

What year are you looking at? I would steer clear of  early 2007.  The first AFM engines (active fuel management). They had LOTS of oil consumption issues. They are good motors though.

The 5.3 is a late model small block. If you're afraid of rpm to make power you won't like it.

I've had a couple, and like all GM small blocks they're pretty bulletproof.

I have a 99 Sierra. Put 290,000 on the 5.3. Just put a new one in. It's a great motor.
