Looking for crank for 408 project

I have a few extra bucks and am ready to buy the crank for my 408 project.
Cast or forged is OK.
I'm in Houston (zip code 77027) if shipping is a problem.
I wanted to keep the cast version under $250 SHIPPED if possible.
$500 for the forged.

Maybe someone has one they're not going to use and have laying around their shop/garage?
