put a micrometer on the crank, the bearings, and the main with the cap torqued in place. do the math and see what you come up with. barring access to a micrometer, get some plastigage and check it that way. i do not know what size plastigage you need for a chevy, but one of the bowtie bubbas will know.....

I am sure you have checked it out but there is two different bearing sizes in 327"s. If you had a medium block and small bearings they would be real sloppy in the block. If that is the case you have other problems as the crank is probably wrong.

If it a 68 or 69 block it's a large journal block. You probably have a small journal crank. what are the numbers on the box the bearings came in????

I have never dealt with them but I think there is spacers out there to fix your problem. If you can send the crank and bearings back that would be good but if you are stuck with them a new block or spacers would probably fix your problem.
