You can bore it to stock LS1 bore. I believe that is the max. like 3.903 or 3.905. Something like that. I dont believe a 4" would fly on a 5.3Originally Posted by ULuze2
However that just happens to be stock 6.0 bore though.
That's correct. You would bore the stock 5.3 from 3.78 to 3.90X or about .120-.125. That's the max you can go without running into cooling issues.

So you can bore a 5.3 to 6.o?
a 6.0 is a 4.0 bore if i'm not mistaken
blown transmissions are about as useful as 97% of the guys on this forum
a 5.3 can become 364 CI but it would be a different beast then your typical 4" bore 364

No sir, My point was that if you want a 4'' bore, a much much cheaper way is to get a 6.0 block. And go that way.
yes sir.
Yes, because of a different stroke setup. You would need a 4.1 or so stroke to = a 6.0 lol

Yea the maximum bore will be stock ls1 bores from 5.3 to 5.7. Even a 4.8 can be bored out to 5.7 you'd just have to get the crank off a 5.3 or so on.
