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

 

piston rock worsens after about 85mm and ring seal also becomes less effective. if its a street driven daily car, longevity's sake would like to see 84.5 for the limit. then if required, you have a few more hones left in an already expensive block.
