LS1 parts interchange questions

[V]

Ok, i know some parts change over the life of the LS1 motor but i have a few questions. Ok, I have a 2001 LS1 that threw a rod and destroyed the motor. its still in the car but it looks like the damage is limited to the rod, oil pan, front cover and block. It blew up right upon start up so i am thinking maybe the rest of the bottom end was spared, such as the crank and 7 other rods, pistons, and valvetrain. Motor had 64k when it popped.
Thats the first part, secondly, I have a 99-00? Ls1 engine that was in a z28 that went off road and sheered the bottom off the block.
I was wondering if i get another LS1 block and oil pan, could i take the remaing bottom end out of the '01 and use 1 rod and piston from the 99(or '00) motor? also what exactly are the differences over the years, i know egr system, injector size, etc, but a comprehensive list would help. Thanks in advance.

i know 98 has weaker rods/bolts than 99+, not sure about others like 01-02

Internally they should be the same. 00 and newer had upgarded rod bolts, in 01-02 you could have an LS6 block which wouldn't effect the crank/rods. Before I got crazy I would just look for a shortblock on Ebay or LS1 tech. Stockers are getting cheap, alot cheaper then rebuilding a block

If I remember correctly, the 2001 and 2002 had an LQ4 cam ??

Yea lq4 cam ls6 intake, all parts are interchangeable though

ok, ive looked for shortblocks but 90% are for sale due to certain problems, the reason they were removed, the other 10% get pretty decent prices. I dont need to rebuild a ls1, i would just have it sit as a spare engine to use for a future project, possibly to stick in my Denali when it hits 90k miles. i'll keep my eyes open for a complete shortblock for now.

That's the best way to go, you can only safely bore an LS1 .010 over, so it is risky doing a rebuild. I'll keep my eyes peeled for you as well.
