I can't blame nooone for wanting to machine a crank for you from a steel billet - it's a stupid idea! Even a cast steel crank will have better grain structure than one machined from a billet. Not only that but there's no way you'd be able to machine a billet down to the shape of a crank without it distorting. There would need to be a lot of post-machining heat treatment and reshaping of the crank to make it sound, and even then I wouldn't like the chances of it surviving high revs for long.
Also do you even know what 4340 means?

Have you never heard of a billet crank before?

Properly done billet cranks can be and are the best around. How do you think they make Formula 1 cranks? cast them! haha
Very expensive though, especially when you start with a chunk of forged steel...

I actually wondered about F1 motors - I would think that forging them would be much better than machining from billet, especially if you have the budget of an F1 team - and I'd expect machining one would cost a lot more than $5K (unless you did it all yourself)
