i was just wondering if there was a difference in max. potential bore sizes of a sleeved ls block, or a sleeved b20 block. i already have the ls, but i am looking to go as big as i can, so i thought maybe someone could help me out. thanks

 

Blocks are the same from a Ls to a b20b/z, only thing honda changed is the stock sleeves 84mm for the b20 and 81 mm for the Ls. If you are going to sleeve it,the block code's will not matter , unless you want a b18a sleeper engine
