70 340 HP handling ability.

Most people say the stock block is good for 600hp +/-.

I've also been told that using the outer holes on the four bolt mains is a no-no because the stock block is not thick enough to support the extra bolts. Better to leave them out or cut the ears off

Does that apply to the splayed main caps also? I thought that was why they offset the outside bolts and angled them to an area that was thicker. Not arguing I just don't want to do this twice and already have the main kit.
