Ritter 59 degree iron block

<<<"rrvolare is about to find out a stock big block making an HONEST 650 HP has a very short life span.">>> Boy i would love to see a well known ENGINE builder on this site pipe in on this quote ... A WELL built stock block BIG BLOCK making 650 HP and will say just under 700 TQ naturally aspirated has a short life????? IF that was the case then the engine builders might as well close the doors ... you cannot tell me majority of big block mopars running in the 10 second bracket have an aftermarket block... I do not know of one person running a 400 or 440 in the 10's having an aftermarket block .... Hemi is a different story ..
What does short life mean ???? block cracking ??? rod failure ? please elaborate ... because if this true ... i might as well switch to chevy or ford ... Then what is safe on a big block stock block ?. 500 -550 HP ... the smallblock stock block is capable of handling that hp ?
