Is this a new or a used engine?

If new, then it sounds good. What are your goals?

If used, then what do the main and rod bearings look like? Any gouges or noticeable wear? Do the cylinder walls still have a good amount of cross-hatching left in them? Any Scratches or groves?

Its a new and my goal is get close to 400hp or little more

I guess its a fresh build

I'd be wary of using a cut crank. There's going to be a few who come out of the woods claiming it worked for them, but with cranks a dime a dozen, I wouldn't chance it. Even Bogus would recommend uncut.

He saids its to factory spec

You my friend are right. I broke a cut crank back in 2007 and never used another one again. Just my $.02 A used factory crank can be found for around 75.00 to 125.00 dollars http://www.dsmtuners.com/forums/cylinder-head-short-block/268533-broken-crankshaft.html

If you keep the crank at .010 under size or less than it will be fine. I much prefer a .010 fresh cut and polished crank to one with 150k+ miles on it. A good straightening, grinding and polishing and balancing will give you very good results.

Yeah we all have to go with what makes us feel good The one in my current setup has about 150,000 on it. I had it micropolished and cleaned. breaking that other crank early in the dsm game has made me shell shocked about turned cranks. Bryan I always value your input and if you say its okay to use one with minimum tolerance then its all good

 

[DoggTalon]

Your trying to tell me you think it could be a broken crank or what are you saying

 

[Miasma]

He's not saying your crank is broken. They are saying that in some cases using a crank after it has been cut that it has broke. If your crank has been polished an is still within spec you'll be fine.

So then the motor wouldnt be a bad idea to pick up

as long as it looks good as everyone else explained.

How do you know if its looks good or not

Well it is really impossible to know if it will be a good engine or not. That is what happens when you buy random engines from random people. One would have to physically take it apart and measure everything to verify that it is a good engine. You can either take a chance on it and buy it like any used engine, build one yourself, or buy one from a shop that specializes in these engines.
