500 hp is pretty low the average 408 making that plus now with TF's. The problem is in this 12 year old thread there's been 5 or so ? 700+ hp engines raced often posted, that's promising but not exactly proof, more examples are needed before the general consensus is these engines are capable of X HP. I remember when people were afraid to make any decent power with cast cranks etc.., it take a bunch of people over time pushing known/perceived limit's.

To me the general consensus of this thread is 600-650 NA hp is proven somewhat safe.

I think we have to remember that there are wayyyy more people doing this stuff then on here. Its always a snapshot of the bigger picture. I get what you are saying though.

Personally with good machining and tuning I don't see why 700hp N/A wouldn't work with a stock block. I know compression is usually higher to make that power in an N/A combo, which can be a killer itself, but its all in the tune just like it is with any sort of power adder making that or more in a stock block LA combo. Atleast, that's my line of thinking.
