I am going to do an engine build over the winter. I am curious with peoples experiences and opinions. I am planning on building a pretty stout engine with a fairly large turbo. Will the stock crank hold, should I use a nitriated crank, or should I just go crazy and use a billet crank. I am curious about horsepower strengths on each crank.

Well in my stock 163,xxx mile engine, it had a slight rod knock ona couple cylinders i believe, nothing real bad, didnt make any noise except for start up and up around 3500+ RPM, well i drove it like this from dec to july, when it got real noisy and i just shut it off, well i got the engine pulled yesterday and found that the crank is now is 2 pieces.
I think the stock crank can hold up to some decent power numbers, but id say of your planning on going over 600, than i woulod pony the dough for a billet crank and not worry about it again.

A few years ago, U were talking ~ $2000.+ for a forged crank & ~ 4-6 Mos delivery.
