Stock crank is pretty strong but it would be highly recommended to get it cleaned up by a reputable shop before re-using it. Are you still running the stock balancer? If you decide to run a better unit (ATI Super Damper), be sure to get the following:

- BBC crank hub from ATI for the LT1 (have it machined to fit properly on the crank)
- Procharger spacer machined to work with the new damper/hub
- Timing cover machined for the larger hub with a new seal
- Have the crank snout keyed (double if you want to go nuts)

The benefits of the larger hub are to reduce the stress on the crank snout. Once you start hanging the pulley off of the crank, you will see what I'm talking about. This may be overkill for the time being but if you decide to upgrade the head unit or run more boost, you will be all set.
