The 6.0 isn't that expensive, and it will be less stressed to make into a 400+ cube motor than a 5.7liter. You can always turn the 5.7 into a 383 if you want. Don't get hung up on numbers so much.

Yes a .030 over LQ or LS2 block with a 4" stroke = 408 It is just me but an LS2 block I would just do a cleanup hone like in sig..
W/O sleeving an LS1 can go 382 safely @ 3.908 (post 98 block). 97-98 block only hone to 3.903

Or is that just after the hone and before the 4" crank? That makes sense then.I thought you were saying that the 99+ blocks were 3.908 bore compared to the advertised 3.905.
If you go aluminum, I would only go with a .005" hone and make a 402 or go .010" and build a 404 c.i engine. Going .030" on a LS2 block is a bad idea. The sleeve is going to start getting thing. You can resleeve them or even a LS1 block but that is going to start getting expensive quick. If you are wanting an actual 408, the LQ4 or LQ9 blocks are the way to go!
