Hey dudes, how far can you safely overbore a 2001 4.8/5.3l block, without ultrasonic testing or anything crazy like that?? I have a 4.8L complete engine and want to build a 408-ish motor.

I was just asking to see if it was even an option, a little pre-planning if you will.
Also, where I live, 6.0L blocks are NOT found for $400. A decent entire engine must normally be purchased, and basement price on that is usually around $2000, from wreckers.
In Canada prices are different, and its harder lots of times to get the prices you guys get. A fresh 6.0L block right from GM there is like $5-700, here its like $1500. Not very fair.
On top of this, all "LS1/LS6" engines get hoarded by an Fbody 'speciallist' that absolutely rapes people for them. He usually charges $6-8000 for a LS1/T56. Which is absolute insanity.
And besides, I mentioned that I was curious about building a 408ish motor, which no matter what block I use, 4.8/5.3 or a 6.0, Ill have to "spend thousands on a stroker rotating assembly" anyways.
