**600hp sbm block limit? Or is it bs!!**

What I getting from this is an under 600 NA hp street strip especially one that's not seeing a lot of strip stock block should be no worries. A 600-699 hp drag race engine should be able to use stock block you may be running borrowed time, doesn't seem like of people are showing a lot of examples failures though, so might be fine, 700 + hp I imagine not a ton of examples out there still haven't seen people post failures but probably should be budgeting an aftermarket block at this level. And power adders might be able to squeeze more?

IMO, usage dependent. I wouldn’t push it that high myself N/A all day long.
In another point, how many people period, not just here, build small block MoPars into 650-700+hp range? Could this be why you don’t see a high failure rate? Even if there is a failure, do you post up every bit of fix bit information?

A power adder like a turbo is a lot safer of a power adder.

Whoever he is , he ain't no greenhorn. He's got a valid point.
I for one wouldn't push a stock block over 650 hp and expect to pound on it long term. But that's me and my money.

A valid point indeed.
