I can understand and get on board with that. The concern he is having is, where does the stock block give up and I think that is more in the reliable area rather than splitting it in half for power.

At the moment, I can’t remember who started the thread a way back on block strength. Something like
“Is 600hp the limit on stock blocks” thread.

In reality, 600 is a lot for a stock small block. Actually, it’s a lot period for a small block, race block or not. Not many people go there.
I'm all for guys making more power and going faster, I'm guilty myself, but it's just not smart money to chase 600 hp and up type power while still utilizing a stock block platform. Yeah there are a few guys that use them and run fast, like John, BUT his cars are very very light compared to most others on here so just how much power is he making? If I recall correctly I don't believe he dyno's any of his stuff as he is looking for track results but the point is still the same you have to have a foundation that will give you peace of mind and that you can actually grow into over time too if a person wishes.
