Stock Crank/ much HP too much?
What is a safe power level for GM factory crank and rods in a Gen1 SBC? I am looking at around 400HP when all is said and done.

400 hp
u'll be fine... i'm gussing u have a 2 bolt mains ??? i've never had mine dyno'd but the way it put together i'd say 300+ in my motor..

I figure 400HP is OK, but not much more over. The block is a 4 bolt main.

4 bolt mains....
knock yourself out... a friend had the same motor but really worked with blower... dyno'd 750hp... so 400hp will be no problem.
