I was wondering if I build a 406 stroker when buying rotating assembly. I found an entire eagle kit its all forged except for crank its cast my question is I want to shoot for between 500-650hp with set of dart pro 1's that have been worked extensively would that be possible and if so would the cast crank be good for that? Or should it be forged to it will be in my 64 chevy2 station wagon street car no racing and no nitrous. Any help or advise would be,greatly appreciated. Sorry for long post
