Anyone care to list them for me, please? Thanks!

 

Cylinder heads, Cam, Valves, Valve Springs, Oil Pump, Oil Pan (C5 specific), Intake Manifold (depending on year...'01+ LS1's use the LS6 manifold)

 

Guess I should be more specific, '04 LS1 and '04 LS6. Just seeing exactly what differences my car has from an '04 Z. And thanks for the reply, Yelo.

 

As far as I know the differences should only be the Heads (casting and valves only...springs are the same), Oil Pump and Oil Pan.....

 

i believe the block is different concerning the oil passages and such but they're both interchangable still.

 

You are right, but he may have a ls6 block. Some 01 and 02s have them and many of the 03 04s have them. So he may have one anyway.

The cam in a ls6 is different, exhaust manifold, cat-back, air box.

As far as your car goes there are tons of differences

 

I know there are tons of differences between the cars themselves, I was just wondering about the engine. Thanks for all the replies, btw!

 

different pushrods as well in an LS6, higher compression ratio too.

 

the orignal LS1 piston was made by Mahle using a alloy called M124... the LS6 got pistons made of M142 (more copper and nickle)... this allowed tighter bore clearances.


but thats when the LS6 first came out.. i dont know if all genIIIs have them now or not. knowing GMs modern rep for updating everything GenIII that proves itself, you probly already have them...
but im not positive.
