Shimming main and rod bearings?? Am i crazy?

[twentyover]

Building a quasi hot-rod European Ford motor, a Cologne V6. Known in the US by displacemenst of 2.6, 2.8, 2.9, 4.0, and 4.0 SOHC.

I'm going to use a word not often heard in Pro-Touring- Budget. I'm using Clevite Michigan 77 bearings, and am finding clearance with standard mains is just a skosh on the high side- it's coming on about .003, 5 tenths over specification limit. Looked for .001 oversize mains to close it down to .002, but they appear to be unavailable.

I'd rather not cut the crank. I seem to remember hearing somewhere that people have shimmed the back side of a bearing shell to get correct clearance.

So am i nuts? (although that doesn't really have any relevance to the question presented.) Anybody done this, or have any recommendation how to close the clearance down a little, or should i just blow off the deal since I'm only out 5 tenths. All input appreciated, and will be considered, even if in the end i ignore it.
