Ok, I have made about a million posts about this engine build up but eveytime I come close to deciding exactly what components I want, I come to a point that I have a question about something. Its going to be most likely a 331. Well heres my question and it should be the last because I already decided on pistons and rods so the crank is the only thing left. How much power can a nodular cast crank shaft handle?? I am using a stock block so Im really not going over 500hp. Will a cast crank be strong enough??

OOORAAHH!!!
Yes, more so if you use "lightweight" forged pistons and rods.
Around 450 FWHP will be a safe power level.
Use a gridle to reduce oil drag over the crank and increase block strenght.
Crank power handling.
