Be aware that blowers place side load on the crank snout can snap the crank between the snout and #1 throw. Which is why you don't want a cheap crank!

- 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.

much appreciated guys, i think im going to ditch my rotating assembly and go with a forged kit and also change the balancer, i will take a note of all these things and talk to the machine shop i go to.
