flywheel to small

73 vette with 350 stock engine low mileage car. I have two stock flywheel replacements luk and hays and they will not fit over end of the crank. They are .002 to small. I have confirmed that they are the correct part number for my application. The crank measures 2.484 the flywheel measures 2.482 The old flywheel I.D. measures 2.486 Why me.

I had a balancer that was .004" smaller than the crank snout and that is how I got it installed without damaging the hole in the balancer.
I also chamfered the crank snout just a little with some sand paper so it would slide on without catching the inside of the hole.

Use a rigid hone and hone the flywheel crank hole just a bit. Check it frequently so not to remove to much. A slight press fit would be great.
