Re: LS1 vs. LS6 block??? (Bone_Stock)
For years '02+ The difference is around 50-55 Cran ponies.
This can be attributed to :
1- Open Intake Port ( actually little more than current C5 )
2- Better Heads
3- Lighter Valve Train
4- More aggressive cam
5- Better Short Block
6- May be the TI exhaust :skep:
That is about it.

Re: LS1 vs. LS6 block??? (kewlbrz)
Even though the blocks where shared heavily(typically, LS1 spec'd vehicles got an LS6 block), the LS6 block I believe still only got the additinal machining to open the bay to bay windows more when built on the LS6 line. The LS6 block is cast from a stronger material, but I have heard a few vendors like the LS1 block for resleeving...

Jason Squires on here also had this to say in a late 01 post here:
"F.Y.I. During a tour of the St. Catherines, Ontario GM Engine Plant (where our C5 engines are built) we learned that our LS1 block will be replaced by the LS6 block."
Part numbers are also shared as well.
