I need a new crankshaft, and this is the best deal I've found. Does anyone know if this is a decent name brand, or if there are any better deals out there?

Cranks you can rely on and afford.
If you need a crankshaft that's dependable, but don't want to empty your bank account, Eagle Specialty Products has the solution. These cast steel crankshafts for Chevy feature .092 radii on rod, main journals, rear seal, and snout for increased strength. Crankshafts for Ford have .125 radii on all rod and main journals. Each crank is inspected for dimension, size, and stronke accuracy, has a journal finish of 6 R.A. or less, and has a target bobweight of +/- 2-percent for reduced balancing time.

Thanks

Yes Eagle is a good brand name. They are used in race engines all the time.
 
I've heard stories about the Eagle cranks breaking. I have personally used the Scat cranks before with no troubles and have heard they are much better than the Eagle cranks. Don't take my opinion though without researching it. This is just my personal experience.
 
From what I have "heard" both scat and eagle cranks are made in Korea and I have heard of people having trouble with them (way out of balance, not straight, etc.). I went with a forged 400 crank that had already been turned down that I found locally for about what that crank costs. Now, given that, there are probably more people that run Eagle and Scat cranks than anything else so they can't fail very often.
 
My crank is a cast Eagle single piece rear main 383 crank. Balanced up just fine, no problems with it what soever. I'd bet the "not straight" thing is people improperly storing them somewhere along the shipping line.

Haven't even completed the engine yet so I can't say if it will break, but I'll let everyone know if it does.
 
For a daily driver an Eagle would be fine. If your right foot gets heavy and your RPMs get high spend the extra money. I have had them in my mustangs and have had OK luck but went to a better crank and could definetely be harder on them.
 
Forgot to mention that the only other reasonable option you have is to find an old 400 crank and have it turned down. Companies like Lunati make 3.75" stroke cranks but they are like $1500 :eek1:.

heard horror stories about them and replacement issues too. Enough so I'm not sure I'd deal with them.

If you're talking about a factory 400 chevy crank with the mains machined down .200" to fit the 350 block i've got news for you. GM never made a forged 400 crank so someone must have told you a story when they sold it to you. Not trying to be a prick, just saying that you were lied to if that is what someone told you.
 
The part that says "had already been turned down" That leads me to believe he is talking about a factory GM crank since you have to "turn the mains down" in order for it to fit a 350 block. It is entirely possible that i misunderstood what he meant. Maybe he meant that it was all machined and ready to install but that's not how i interpreted it.
 
Well I have a 400 sbc with a crank that cannot be turned down anymore. The rod bearings are already at 40 over/under. I found a local seller with another 400sbc for sale, but he's kinda shy and wont get back to me. And even if I got another used one, it would still prob. need turned down= MORE money into a used one. This would cost $199 to my door, which isn't too bad if the quality is ok.
A local speed shop said they could get the Scat crank for $179+tax+shipping=$250. But no one has come up with a link to a better priced one.
The feedback seems to indicate that the Eagle crank may be pretty decent, of course there are better ones, and everybody has their favorites. But I haven't seen any links to a better deals, so if this bashful local seller dont get back to me by tomorrow, I'll probably order it one.
Thanks guys
 
a local shop is going to charge you shipping??? f that. Tax I get, but I have never heard of a shop charging shipping to an in store customer... If it weren't for that I would say get the SCAT crank from them.

When I was sold the crank I was not told that it was forged. When I had the rotating assembly balanced the balance sheet said crankshaft type: Forged. That's where I got that. Is it possible that it could be a Pontiac crank (from a Trans Am, for example) and that only the Chevy cranks had to be cast (I have no idea if Pontiac and Chevy cranks interchange)? It really doesn't matter to me anyway, I don't need a forged crank or anything.
 
Pontiac cranks are different than a chevy crank. Like you said, really doesn't matter anyhow but i was just making a statement about the whole forged 400 crank and assuming that it was supposed to be a factory 400.
 
Now ya got me looking on EBAY:eek1: :eek1: . I like the security of buying from Jegs or Summit, and I'm a bit scared of gettin screwed on Ebay. But this one does fit my budget better.
Anyone heard of this brand?
