72 Demon slanty-to-340 Resto

To be perfectly honest, unless you plan on spinning it to the moon (routinely north of 6500 on purpose), or feeding it copious amounts of nitrous, or both, get a cast crank and roll...I can't think of a time I've heard or read about where a cast crank actually came apart in a 318...apart from power handling capability north of about 450-500, the only thing that forging will net you will be a lighter wallet.

EDIT: Ya know what? Come to think of it, there's a member on here who has a turbo'd 360 pushing 9s...pretty sure he's running a stock crank
