differnece between 5.3/ls1/ls6 block
differnece between 5.3/ls1/ls6 block what are the differences between the 5.3, ls1/ls6 block besides the obvious bore from the 5.3 to the ls1/ls6? are the oil passages different, one stronger than the other? planning on doing a boosted forged 5.7 and want to buy a new block bc i got burned on my old build buying a used block. theres a slight price difference between the 5.3 and ls6 block so i was just curious if there are differences with the ls6 that its a must to get.
I have the LS6 1168 It has bay windows to equalize windage pressures. I think that's like loose underwear.
Ls1 does not. I read somewhere that the 5.3 bored to 3.9 makes the strongest aluminum block. I don't know much about 5.3 though.

I don't think the 5.3 block at 3.9xx bore is any stronger than the regular 5.7 block.
If you leave the bore stock sized then yes, which alot of people do when boosting for that very reason.
