LS3 was the peak IMO; the DI versions are overly complex for not a whole lot of additional potential.

I've done LS1, LS6 and LS3 swaps into various hot rods with great results. Engine and trans control wise the 24 tooth reluctor wheel LS engines needs one ECM for the engine and trans. The later 58 tooth reluctor LS engines need two ECM's for engine and trans control if you are running an auto.
A 2000ish 6.0 iron block with a stroker kit and LS3 heads is a good combo that doesn't break the bank. My one of my current hot rods is a 98 Wrangler with a rebuilt LS6/4L60E combo and has been bullet proof for 15 years.
My current project is a 80 Camaro with a 2012 L92/4L60E combo. The L92 is dressed to look like a LS3. I just got it tuned and it runs great.
Really depends on your budget and goals with your project. I am believer in build it once. Don't band aid stuff.

I really like my L33, compact, lightweight, vanilla motor , gets great mileage in my jeep and with a exterior package off a express van (intake, injectors coils etc, front mounting stuff... ) It ran first crank with the default 5.3 tune on my Holley Terminator Max.
Factory rebuilt (ATK via Jegs..) < 3500 for the long block. The L33 gets a Specific Truck cam that pulls right off idle (625 RPM) to 5500, I have the redline set there..
NOt saying its the best, but it is a tidy package.

While technically there, I doubt the difference is noticeable. Furthermore, is that really a priority for these swaps? I seriously doubt it.

GM uses the smaller bore to accomplish better fuel efficiency and EPA compliance. That's the view point I was referring to. If I were doing a swap, I would absolutely get the biggest bore I could find and afford, unless it's an LS7. You can have the LS7. I'll take a 5.3 over an LS7 any day.

To me the 5.3, especially in Gen V format is one of those. The 5.7 is indeed more powerful, but at a cost disproportionate to the size difference. It would be interesting to see GM's rationale for dropping the 5.7. 6.0 and 4.8.

Fun fact…I have a van fleet for my electrical business. My 4.8 vans average 13 mpg’s. My 6.0 vans average 15 mpg’s. We bought the 4.8 vans for fuel mileage. Lol!!
