LS1 newbies looking at casting# 12562374 Hi,
I'm converting from the German engine world and really enjoying it!
I'm considering buying an LS1 with a block casting number of 12562374. I looked all over and can't find the details for this block. Is there a master chart somewhere with all the LS numbers? This engine lost oil pressure and was immediately (i'm told) shut down. I will of course tear it down if I buy it so I would like to know what the specs are.
Thanks,
MosFetMan

I have found 12562174 as an LS1 bock casting number. That is the closest to your number I have found.
Either way, LS1 blocks can't be bored more than .005 over the original 3.898.bore. So check the bores for any wear.
