    There is a number on top of the block behind the driver side head. It's quite difficult to see -- you'll need a telescoping mirror and a flashlight. Not sure about '01s... I thought it was the later '02s that received the LS6 block. I'll go find a part number and brb.

    I think the LS6 block number is 12561168. Will double check.

    also if you look in front of the passenger side head the ls1 block will have a little bullseye mark in the casting. the ls6 does not have it

    You mention LS6 intake and its my understanding all 01 and 02 F-body's with the V8 received it.
    For what its worth-I have an article from a Mag I cut out that mentioned about 15% of 01's have the LS6 Block and about 25% are in 02's. It also mentions of possibly being able to tell by the luster of the block, a Nemak Engine plant block casting is duller=possible LS6 block and a Montupet plant is shinier=LS1 block.
    Have fun trying to read them numbers with the cowl overhang.

    241 casting number is simply for the head -- doesn't tell you anything about the block. I was able to read my block number from beneath the car utilizing a telescoping mirror and a flashlight.

    One thing Pajeff02 didn't mention is he has a sweetass garage setup with a lift making this easier.

    Even with a lift it wasn't easy.

    Casting number is on the back of the block behind the driver side head. Go at plug number 8 from under the car -- much easier than from the top. Also, for better access to the other plugs, remove the coil packs. One connector and a couple of bolts is all.
