racerp419- If your racing that engine and it does indeed put out those numbers then I would say You are pushing it on the bottom end. You didn't say what block you are using either, or the weight of the car. Most unmodified bottom ends will take that kind of power for a while, then it's expensive smoke.
Studs and a Blue Thunder steel main girdle are cheap. USE THEM I would. BTW- welcome to the club!
