ok well my g8 is getting up there in miles 158k and dod is still working I would like to do a nice budget build I came across a low mil 2009 5.3 motor for $500 or a swap for a set of c6 vette wheels I have I know
going from a 6.0 to 5.3 or even a 4.8 is a down grade but its looking a lot cheaper build I been seeing pretty damn good numbers 420-460hp tuned just seeing what u guys think I been also thinking going the turbo route cheap 4.8 or 5.3

I am curious, what is wrong with your motor that you're considering replacing it?

When I pulled my heads off, the factory crosshatch was still there. The heads were in remarkably good condition and required no machining. By and large the block was in excellent shape.

Well my motor is fine it does burn oil I get some lifter tick but I would like to swap something else in while I slowly build the other motor I just don't wanna be down a car that all

 

[Jova007200]

I see... I understand.

I was lucky enough to have a beater car to drive around while I've been doing my work. No point in selling it since it's garbage anyways... but it works...

Anyways, there are other reasons for oil consumption, though. The valve seals are largely to blame after so many miles, as is the PCV system especially with the driver's side rocker cover if it is not updated. There is a service bulletin out on it for that very reason.

That 5.3 will still have DOD.

ive had the car a few years now its lowered on coilovers full exhaust tuned all that but I would like to get some power out of the car but the other motors came to mind since a 80k l76 is going for 3k and ls3 5k and 4.8/5.3 400-1250 and they both do pretty damn well with boost

No replacement for displacement

You could probably find an old beater car that you can unload fairly easily once your project is done for about the same cost as you purchased it for..... for what it's worth.

Yes there is, it’s called boost. Otherwise I’d have a 600+ci engine.

Would those motor be a direct swap beside swapping the recluctor wheel

Or compromise. 417ci + 15psi is pretty peppy.

Pretty much we’re I’m at. Procharged 402, 14psi

If the 4.8L ever came with a 58x reluctor wheel, which I’m not sure it did then it would be, a little bit of research shows that certain 5.3L came with the 58x which would make it a direct swap.

I'd do this. That way you have a beater, can take your time, and have a spare car in the future when the G8 is down!

My thoughts exactly.

And Mr. Jones.... don't let anybody say your beater car is ugly. It's not ugly, it is seasoned. It's not unreliable, it's 20 years old and it's a friggen tank!

I forgot to add.... nothing compares to blaring Molly Hatchet (you know the song) in an old beat up Sable like you just don't care...

i found a great little write up on the l96 motor pretty muchis was saying itwas a direct swap for the g8 has anyone ever used this motor or have any info on it im looking for a shortblock i can refresh or rebuild hi comp piston and rods keep it stocked cubes

 

[Ls3BeautyBeast]

There is this 5.3 G8 I found on Youtubes is running in the 9s

Some experience i can share, it's kind of apples to oranges, but respect the 5.3! I had a budget built jet boat, ran a stock 5.3 truck engine if i remember correctly it was the lm7, with unknown miles VS a new Ct525 in identical hulls, with same pumps, i ran at 62mph all day via GPS speedo, 6.2 ct525 ram same top speed. They are torquey little monsters.
