there are 2 different 5.3's 99-02 are 323 CI and 03-06 are 325 CI
which is basically the difference between the L33 and LM7...2 Cubic Inches
but you can still choose between the L33 and LM7 today so that is the difference between the 2...but as far as 5.3s go the LM7 became the dominant engine in 2003 and the L33 is known for its lesser Horsepower
Also w/ the 5.7 94 and up is actually 355 CI also known as the LT1...i believe the LS1 also is 2 cubic inches bigger but im not entirely sure about that...i believe its the same engine block just upgraded cam, intake manifold and heads
as far as 4.8s go i believe the same goes...there is a 292 version and a 294 version but the smaller of the 2 is not available anymore...just like the 5.3 it had the smaller version when the conception of the NBS came through in 99 but unlike its older brother it grew 2 cubic inches and thats it...no 2 CI smaller version available...not that anyone would want it but hey
this is just what ive gathered from GM...im not sure if its entirely accurate but im pretty sure most of it is...same here basic ballpark...with a little more accuracy

LT1 is indeed a 350 as shown here. http://www.grandsportregistry.com/lt1vslt4.htm
It is quite possible that it may be bored .030" over to acheive a 4.030" bore which would make it a 355ci.
As for the L33 and the LM7... the difference is not in cubic inches but in the material the block is made out of. There is also a bit more compression to the L33.
LM7 block is made of cast iron and has approx 9.5:1 compression.
L33 block is made of cast aluminum and has approx 9.9:1 compression.(thus making more Power than its LM7 brother. Thats why this 5.3L is known as the H.O.
As for the LS1....yeah, LT1 and LS1 are 2 completely different blocks. Might wanna read up on that. The LT1 is a Gen II small block whereas the LS1 is a Gen III small block. You know, you have a Gen III block in your truck according to your sig.

The LM7 uses a 0.456/0.456" I/E lift cam with 9.49:1 compression while the L33 5.3 uses a 0.482"/0.482" I/E lift cam with a 9.9:1 comp ratio.
The LM7 has never undergone the 2 cubic inch change that you propose, the LM7 has ALWAYS had a 325 cubic inch displacement with a bore stroke of 3.779" x 3.622" and had 5.3L of displacement from 1999-2006. I assume that your GM source simply is rounding the 5.3L to either 325 or 323 cid, but there has been only ONE bore stroke combo for the 5.3 and 4.8.
Both the LM7 and the L33 are available in 2006 and 2005. The LM7 with its iron block and aluminum heads is rated at 295 hp and 335 lb/ft of torque, the L33 is rated at 310 hp and 335 lb/ft of torque.
the L33was also available in the SSR in 03 ans 04.
Your comments regarding theLT1 are also incorrect, the GEN 2 LT1 1st came in the1992 Corvette, was a speed density unit, no MAFS, had a 4 bolt iron block, aluminum heads, and it has same bore stroke as theGEN 1 350 did in the 60's with a 4" bore and 3.48" stroke.
In the F-body Camaro Firebird theLT1 started in 1993 it was a mass air setup, with a 2 bolt main iron block with aluminum heads, it was rated at 275 hp from 1993-95. In 1996-97 the F-body LT1 cars recieved dual cats and a slightly different cam which gave them a rating of 285 hp(305 in theWS6 Hawk and Bird and the SS Camaro.
The 93-96 LT1 Vette was always 300hp and mass air.
In 1996 the LT4 was introduced. It was underrated at 330 hp @ 5800 rpm and 340 lb/ft of torque at 4500 rpm. In reality this engine produced 360-370 hp at the crank and the rev limiter was et at 6412 rpm.
the LT4 was the last hurrah for the traditional 4"X3.48" 350 engines, it was used in teh 96 Collectors edition Vettes, in 1000 96 Grandsport Vette and some 1996 LT4 Corvettes. The LT4 was only available with teh 6 speed manual. In 1997 GM installed the LT4 in 33 1997 LT4 Firehawks and 99 1997 LT4 SS Camaros.
In 1997 the GEN 3 LS1 was introduced in the Vette, with a 345 hp rating and 375 lb/ft torque(manual trans) and 360 lb/ft torque rating (auto trans).
In 1998 the LS1 was fitted into the F-bodies, in teh camaro/fbird the LS1 was rated at 305 hp Z28, Formula and TA, and 320 hp in WS6 Formula, WS6 T/A and Camaro SS.
Again this engine was underrated and was actually dynoing from 290-315 rwhp 348-380 hp at the crank.
The LS1 was an all aluminum block and heads, with 6 bolt main caps and coil by plug ignition. It was called a 5.7 350 but in reality it was a 5.6L 346 ci engine with a bore/stroke of3.893" x 3.622".
the GEN 3 LS1 last saw action in the 2004 Vette and 2004 GTO, the new GEN 4 LS2 6.0 took over with its 400 hp/400 lb/ft of torque.
NOTHING between the GEN 2 LT1, LT4 is interchabgeable with the GEN 3 and GEN 4 engine families.
These GM pushrod engines sure do kick *** NOBODY builds them better.

I wish I could find that website that explained all that

The LT4 was only available with teh 6 speed manual. In 1997 GM installed the LT4 in 33 1997 LT4 Firehawks and 99 1997 LT4 SS Camaros.
In 1997 the GEN 3 LS1 was introduced in the Vette, with a 345 hp rating and 375 lb/ft torque(manual trans) and 360 lb/ft torque rating (auto trans).
In 1998 the LS1 was fitted into the F-bodies, in teh camaro/fbird the LS1 was rated at 305 hp Z28, Formula and TA, and 320 hp in WS6 Formula, WS6 T/A and Camaro SS.
Again this engine was underrated and was actually dynoing from 290-315 rwhp 348-380 hp at the crank.
The LS1 was an all aluminum block and heads, with 6 bolt main caps and coil by plug ignition. It was called a 5.7 350 but in reality it was a 5.6L 346 ci engine with a bore/stroke of3.893" x 3.622".
the GEN 3 LS1 last saw action in the 2004 Vette and 2004 GTO, the new GEN 4 LS2 6.0 took over with its 400 hp/400 lb/ft of torque.
NOTHING between the GEN 2 LT1, LT4 is interchabgeable with the GEN 3 and GEN 4 engine families.
These GM pushrod engines sure do kick *** NOBODY builds them better.
