are theses cranks any good im looking at (44003800 4340 SBC 400 mains, 3.800" stroke $495) for a 400sbc with twin turbo.

That's a good crank for a non-turbo engine. I'm not saying it wouldn't work, but for piece of mind I'm running a Callies magnum in my twin turbo.

How much boost are you throwing at it? They sell a forged blower kit assembly. I plan on running their kit in my car.

This raises a related question I have (and at the risk of hijacking the thread, I'll ask it). I have heard a number of people warning about staying away from foreign made crankshafts (those made in Taiwan, Korea, China, etc.) to the point of someone actually telling me they would rather have a stock 400 cast crank over a foreign 400 forged crank. Is this just a bias that we tend to have towards products made in the USA, and in reality foreign manufactered parts are fine? How do you know where the various crankshafts are made? Few of the websites tell you that kind of info. Other than calling and asking, how can you tell?

Thanx in advance.

Again, sorry for the slight hijack.

Its hard to tell sometimes! I often use the price as an indication of quality. "You get what you pay for " kinda thing. Both Crower and Callies claim they use USA made blanks and forgings, don't know about other companies. You can definately tell the difference if you have to do any machine work to them. Overseas cranks have porosity and hard spots in their material, yet I have never had one fail in an engine. Some cheaper cranks also require a lot more $$ to get them to balance.Hope that helps.
