How much HP can the lower end of a L98 350 motor handle? I'm thinking about some crazy ideas for power. But don't want to destroy the motor in the process.

Its good to around 400HP. a little more if it's only for short busts and not all out racing. It is a 2 bolt main block, cast crank and cast pistons nothing special.
