4.060" bore why or why not.
alright guys im looking into a 6.0 for the truck..
since i am planning on getting a motor completely rebuilt, i figure why not bore it .03 or .06.
i haven't heard anyone using 4.06" bore, will my temp be higher like the problem guys run into with iron 5.7's.
whats the capabilities of the cylinder wall on a IRON 6.0 block..
any info is good guys, thanks.

EDIT: this is for a DD N/A mild setup, im shooting for 400rwhp..

I think alot has to do with the fact that is something would happen internally, maybe going with a smaller bore, you could resort to the .06 bore to save the block.. I am not sure how much you can safely go on a 6.0, on the 5.3's you start getting very thin on the cyl walls.. Your not getting that much more out of it, why not just stroke it if your looking for the extra cubes??

There is no issue doing a 30 over motor.. But once you go 60 if something should happen, you are not going to have much to over bore it if a cyl is messed up.. Strokers tend to burn oil more so then others. Alot form what I gather is improper piston, rod set ups, which cause alot of piston rock at the bottom of the stroke..

I agree, no problem with a 0.030" over bore. But, going 0.060" might be pushing it a bit, thinning the cylinder walls, etc. Generally, I like to bore out a block just the minimum, that way you can bore it out again later if needed.
