Magnum shortblock capability.

I heard the magnum block is stronger from a local machine shop owner/ engine builder who has forgotten more than i know.
Is it OK if i repeat his info. Its the guy who built the stock stroke 360 with victor heads that made 771


It would be nice to see that dyno queen hit the track and see how it holds up to 7 years or so if racing. Be nice to see what numbers it could produce while building a track record
