360 magnum. Safe boost rumours. True or false?

Are the magnum cast hyperecutectic pistons better than the older cast LA pistons. That's the info I have read in the past so I hope its right or I might have placed too much trust in them with my boost and HP.lol
Any hypereutectic cast piston will be a lot stronger than standard cast, new or old. This is what makes the factory magnum short block such a deal when building an engine. Factory 9-1 hypereutectic pistons with moly rings...price that for an LA 360. Then there is the roller cam:thumbsup:
