Not Ranked
Keep the horsepower around 500, make sure the reciprocating assembly is well balanced, and use main studs. You should be fine.
I've heard KC and some of the others say that the blocks want to split between the mains and cam bearings with over 600hp and high revs.
BTW, didn't you say you had a 406? I thought the 406 blocks were cross bolted.
