Cast versus Forged?

Honest, I hit search before posting this question as I figured its been asked many times. Call me lame but I didn't find it. Okay, it will be a street driven only 68 Barracuda 360 with some minor mods (auto tranny) and I'm hoping to be in the 300 to 350 hp range. With that in mind, would the extra cost of a forged crank over cast be worth it? Thanks. You folks are building my future engine one post at a time.
Cast will last , should be fine
