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 5.3Quote:

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.Quote:

a 6.0 is a 4.0 bore if i'm not mistaken
a 5.3 can become 364 CI but it would be a different beast then your typical 4" bore 364
No.Quote:

6.0 or turbo ftw............. or 6.0 AND turbo ftmfw :burnrub:
You can bore and stroke a 5.3 block to a 363ci or 6.3L, but like said, no 4" bore.
gotta get a Ford for that ................... :bow:
363 would be a 5.9 or 6.0. Not a 6.3Quote:

Plus if anything catastrophic happens with the bored 5.3 your screwed whereas the 6.0 can be rebored a couple times. Unless of course you have a specific reason for doing the 5.7 bore. In that case stroke it to a 363 like quik said. Should yeild much more low end torque.
There are many guys who run the 346 and love them. Good power and great if you are building a low compression boosted motor! I myself like the thought of big cubes so i picked up a 6.0 and eventually will be building a 370 for boost. But as most guys say, I would go no bigger than the 346 bore that way if somthing does happen it can still be fixed( you have a better chance).
you can make a 6.3 out of a 4.8/5.3 blockQuote:
