what is the best forged crank
I've owned both a lunati and an eagle. The lunati had an oil shed coating, finer machining on the weights, and tapered leading edges on the weights. It was also way more than the eagle.

Weight is not a huge factor for us. We need stength. The Lunati is a little heavier in all the right places.
We looked at the Callies next to the Lunati and went with the Lunati.
We could not get some of the options that we wanted on the Eagle.
I have an LS3 with a TVS 2300 that will get a stock stroke Lunati forged crank very soon.

No reason to ever go with Eagle. Especially if you have a manual. They have yet to resolve the issue with the piolt bearing not fitting tight enough.
Compstar is THE budget crank.

How many stock cranks have broken? Anyone know of any?
How about a broken forged crank?
I've got a Cola crank, its supposed to be one of the best cranks ever made. But they dont make them anymore, too bad.

I'm just curious if anyone actually knows about ANY kind of cranks breaking. Seems to be a seriously rare event, no matter which type of crank is used.

Its ALL about the crank breaking, thats the only reason people buy forged cranks for big power builds. No matter how well a stock crank is built or how well the builder preps it and installs it, it will snap like a toothpick with too much power/torque.

There's a huge difference in running a assembly at 10k rpm @550hp then running a assembly 7K @1,500+hp...
While the stock GM crank is strong, and can handle it's fair share of a beating, and is NOT the weak link on a stock bottom end, if you do become a real "player" and start making some power, you will break the stock crank eventually. A Forged steel crank is stronger. Most people that plan on high 10's, can get by on the stock crank, no question. And YES, I do know that alot of people are running quicker ET's with the stock crank. All I am saying is, WHY? When you start making serious power, and sstart running low 10's and quicker, why would you risk it? Has anyone seen what a broke crank will do to your motor? I have. It's not pretty, it CAN take out your whole motor. Block, rods, pistons, cam, water pump (yes, the water pump). I had a crank come apart on me, and did just that. It also took out my oil pan, and STARTER. Yep, when the crank let go, ripped a rod apart and slung the rod through the block and knocked the starter clean off. Broke the mounting lugs. When it spilt the block, it seperated my water pump in half as well. Now, I am NOT saying that can't happen with a Forged crank either. I am saying again, that the Forged crank (and just quality parts in general)gives you better insurance again Carnage like that. Winberg, Scat, Lunati all make killer cranks by the way.
I went with Eagle in my motor, as it was the cheapest Forged crank, and I used an Eagle in my Ford, and I beat it with 1000HP for a couple seasons with good luck.

Boosted 346's are limited to their power/torque output because of the stock crank. I know a couple people that went forged pistons and forged rods with sc'ers and turbos, they are limited by what the stock "cast" crank can handle. Otherwise they would turn up the boost and make 1,200 hp. instead of 700 hp.
