Cast to forged crank

Thanks for everything guys. I have a cast crank 446 that is coming out of my Sport Fury, and will be replaced with a 505.
I ended up with a nice forged crank, and was wondering if it would be worth the effort.
I think I will just keep it as a cast crank engine. It has been a great engine. It went low 12's. I am not sure what I would use it in. I will just have to freshen it up after I finish the 505. Again, thanks.


I would feel safe getting well into the 10's on cast crank...
