Perhaps the installer overtightened them. Use a torque wrench, and dont go too tight.

What 'crank bolts' are you talking about? Rod bolts, Main bearing bolts or flywheel bolts?
"Crank Bolts" is not really very clear.
I'm guessing that it's in a racer as a "fully worked" engine would quite naturally be totally undriveable on the street & if that's the case, you are probably breaking the flywheel bolts when the revs start climbing over 8,500 or 9,000rpm.
It's a common problem.
