you cant bore an ls1 to 355. it starts life as a 346. the most ive seen is a 348 which is something like a .010 or .020 overbore

The max a LS1 or LS6 block can be overbored to is 3.905".

^347 is the max safe bore on a stock sleeved block

i think you can go 3.91" for a 348 but i would just stick with 3.905" 347 myself .
