LS6 Block?
Do you know if you car was an early 01 or later 01 car? Meaning was it built towards the end of production cycle? If so you have a greater chance IIRC...

Blocks appear different because of 2 manufacturing locations, but they're all LS6 blocks.

My experience working on a more than a couple '01 cars has proven that wrong. Won't even bring up my own '01 car
Everything else i've heard read seen its same as the link I posted.
Maybe I'm silly, but I'll go ahead and agree with the guy who helped build the cars.

One more thing though, maybe there were some build-out LS1 blocks yet early in MY2001. Like I said, I'm not sure, call that a guess.
Would've had to have been very early though because my 2001 was built in August 2000, and it's an LS6 block.
