How much power can stock internals take?

[smallv6]

Just like it states, I would like to know how much power
(ET Based) a stock block with stock internals can take before having to go with billet caps or a girdle.
Thanks

I was running 127 mph trap speeds before I girdled mine

figured it was getting close to needing one

I find no use for billet caps on a v6 buick motor
