Not sure of the entire #, but an LS1 block ends in 78 and the LS6 casting ends in 68 Hope that helps a lil....

Well from what i read in Gm High Tech the casting # was 12561168 which is on the left hand side above the tranny flange. So grab a mirror and flashlight. One more way you can tell is that the block is duller in color than the normal LS1 block which is shinier. Hopes this helps.....
