Why are you wasting your time with a 5.3? Just find an LS1 or 6.0 block and go from there. For what you are gonna pay in machine work, your money is better spent elsewhere.

i agree
find a 6.0 and build that instead. youre throwing your money away by stroking a 5.3
just rebuild the 5.3 witha .060 overbore, some 241 or 243 heads and a mild cam.
