ah well ya see the problem there is that the measuring equipment you're using there, will always be insize!
remove the crank and bearings, put the caps on and torque down and measure the bore to ensure these are correct, and round, and not needing a line bore first. check the bearings are the correct thickness for the block is supposed to require also.
bearings in my experience u gotta pay special attention to everything as a slight difference thats supposed to be OEM can through everything out.
or buy proper plastigage to verify the stuff you using is decent. also, are you putting it right across the journal to check its not barrelled etc?
