Anyone rebuilt a 5.3?
I know most people go with the 6.0 once their motor goes. I'm just curious how much it would cost to rebuild a 5.3. I've got one that has a messed up piston but would probably be a good candidate for a rebuild, although it's not totally torn apart yet, so who knows. I think a 5.3 could meet my goals with a cam and converter. I'm just shooting for 13's on motor, no Nitrous.
Anyone make a rebuild kit for these things?
Would also have shorty's (already got), LS1 Edit for tune (already got), K&N FIPK (already got), if I went that route.
I want a decently quick daily driver.

My first question when reading your subject line was, "Why? What's the point?"
If I EVER opened up my 5.3L, it would become a 6.0L (at minimum). There are too many guys with LQ4 and LQ9 pistons laying around in boxes in corners of garages out there for me to not take advantage of it.

On a budget here, and not looking for any more machining than I have too.
I've already got the 5.3 block laying around. Thanks for any suggestions/advice.

differences
the 6.0 and the 5.3 are the same block. i believe the only difference is the bore of the engine. i think the stroke is the same. i might have it backwards. i also read that the 6.0 heads are cast iron were the 5.3 are alum.

It's very doable.
The 5.3 has a smaller bore, which means lots of machine shop labor in getting that done. It would also mean completely tearing down the motor and rebulding it from crank up.
I have a 5.3 that needs head gaskets and maybe a set of rings if you're interested. PM me if you want.

Thanks for all the replies guys.
Maybe I should just try to find a junkyard LQ9 and so a cam and converter.
I'm sure that would meet my goal. I'm just scared of the junkyard motors. I never know how many miles they've got on em'. The one place I know where to get one doesn't have reliable records of that stuff.
PM sent Flyer.

Exactly what I was thinking! Why put in another weak *** 5.3 after you blow the first one. 5.3 suck!
