I recently dissambled my sbc 350 that I had planned to build a 383 stroker out of. It was already bored over .030. There are slight grooves in a couple of the cylinders, Im being told i will need to bore it out to .060 over in order to use the block. I plan on putting quite a bit of cash into this build, and dont want to waste my money on a time bomb. If I end up using this block would it be reliable? Will it be able to stand up to 400-500hp? Or should i just find myself another block? Im a first time engine builder and i want to do it right the first time. I plan on driving the car 2-3 times a week, and the occasional dragstrip on the weekend. Any comments , thoughts, or experiences would be greatly appreciated.
you can just as easily break a std bore block... it's not the bore it's the components and how they work together and your care/use of the engine which will determine how long it'll last... don't worry about the 350 going .060 over... if you are concerned, have it sonic checked. that will tell thickness of bores etc... most cases though a 350 is OK for the .060 over bore...
Is anybody running a .060 block? I plan on going the aluminum head and roller cam and lifters route. Once i get my car together, I plan to drive it like I stole it. With that being said i want it to be reliable at the same time. Im not trying to throw money down the drain.

CNC?-Older blocks with longer ID pad thicker blocks generally?
From what I see the later blocks maybe better because of technology gains, I have about 25 blocks where one cylinder has failed making the block junk for a performance build.
Going by core shift is a poor indicator from what I have seen.
I don't give ill advice or look into the crystal ball I sonic test each block. I move alot of blocks in a years time not many OEM's since the Dart SHP block. When I do have OEM block guys do want them sonic tested.
