Visual difference between LS6 & LS1
Is there a visual difference between an LS1 and an LS6?
I will be looking at an engine that is suppose to be an LS6, and wanted to make sure that it is not an LS1.

The head # is the best tell-tale sign I can think of.

FWIW, I was told by my engine builder that the 03 LS6 blocks are heavier than the previous LS6 blocks... He didnt know where they beefed them up (within the block itself) but he knew it weighed more. So in conclusion, the block was built up somewhat stronger than the 01 & 02 blocks. I have an 03 LS6 block in my car now.
