The bores were .045, .051, .061, .043 on piston to wall vs brand new Wiseco 87mm slugs.
The bore on one cylinder was .043 at the top, .060 in the middle, and .050 at the bottom of the skirt in 100mm of plunge depth. If you have reasons to doubt this I can PM the number of my machinist and he can tell you what he did. Chances are he will call you names and hang up, he's that kind of guy. I was going to leave this off the net but since you asked I decided to give the info out.
For the record, he (our machinist) is the one that solid fills our race blocks and sets up all our piston to wall, we do final assembly. At this point he has more 1050+whp block builds under his belt than there are likely running in America at this time. Archie is old hat at what he does, we pay a premium for his services, and havent been let down yet on machine work. I pull bearings out of a crank that say .25mm on them I am positive I know what I am looking at is not a fresh crank but a turned one. My mic backed it up when I compared to a known std finish crank.

Someone here will figure out why those numbers are erroneous and it was a botched attempt to make myself/ SBR look bad and make you feel better.
In any case, we (Joe and myself) can still help you trouble shoot via email or phone calls if you want - just give us a ring.
Well it seems as if my luck continues...
Some of you may have seen the thread I started about my car not starting up. Turns out the crank sensor was bad. well broken.
The car isnt finished being diagnosed just yet, but right now, we know that somehow the crank is moving enough to cause the sensor to be hit, and broke.

You might want to take this part down, I don't think anyone wants those numbers being posted, and that person is not me for the record. I told the person who posted it to fix those #'s long ago.
