For my L92 427 build, its getting close to the time where i need to pick a crankshaft. My first choice was an Eagle Forged 4.1, but was then told they have reliability issues....

So the other ones are Scat and Callies, but man they are like double the price or more. So whats the real deal? Should I steer clear of the Eagle, or am I gonna have to save another couple months to get one of the other ones?

 

I'm not aware of scat cranks. The callies are only about $100 more. I plan on callies. Eagles are fine, they just may require more machine work than others...but honestly you will probably pay for it with the nicer components too.

 

eagles are good for the money u pay- callies are popular and is a good piece-

scats are not bad-same as eagle imo-

 

A 4.1 stroke in any stock block is a reliability problem if you dont stay NA. Due to the longer stroke the wristpin must be moved even higher up thus creating the need for the ringlands to be moved up as well. This creats thinner ringlands that dont take well to heat.

 

My Callies is on it's way to my house now. Can't beat the quality for the $$$ IMO.

 

....huh?

 

The Callies Compstar is about the same price as Eagle, but its a knockoff made in another country.... The Callies one that was recommended to me was like 2400 and the Scat was 1800.

 

IMO in your application, a crank is a crank. an n/a 427 is unlikely to break any of those cranks.

 

i think eagles are 1000$ and tested to 1200hp

 

Its not really a knock off..It is just forged overseas, then shipped back here to be machined. I am using a Compstar crank in my 402. I brought it to the machine shop that was building my motor, and the owner sayed it was the first Compstar crank he ever used in a build. It was much easier to balance than the Eagles he normaly uses, and overall prefered the quality of it.

 

Well I trust the made in America stuff a little more. So is there anyone that can justify a $2400 Callies for 3 times the price of the Eagle one?

 

Callies crank all the way.

 

And that would be why......? What makes it worth 3 times as much?

 

What is the answer you're looking for? It sounds to me like you've already made up your mind. You say you don't want to go with the Callies because it's forged overseas. You like the Eagle because it's cheap and made in America. You've already been told the Callies is better quality and easier to balance, resulting in less cost for machining.


It's all up to you and what you want to build. Personally, I went with the Callies because I've seen guys running them in 1500 hp applications without problems and although I'm not going to be making that much power, I wanted a rock solid engine that's going to last me and has more potential left in it if I decide to go for more power.

By the way, it's a little confusing to me that you're so wrapped around the axle about where the Callies is forged when your avatar is a GSX-R emblem.

 

Let me help your confusion then. The Callies crank I'm talking about is not the one that you and others keep mentioning. You are referring to the Compstar one. If you read my post you see the price on the genuine Callies is over 2k.


you should read the thread a little more thoroughly next time.




I like the Eagle because its affordable and has a good reputation, and made in the USA. If I wanted cheap I wouldn't be asking this question, cuz I would have bought some knockoff from ebay. Also, a little extra machining cost is irrelevant when compared to the original forging and the quality therin. I do prefer to buy American, because I have more faith in most American products.

As for the motorcycle....dude are you serious? Its a sport bike. I can't afford a Ducati yet, and I don't want a Buell with a Harley motor....so basically limits my choices to the Japanese bikes. Besides, they have been race proven around the world and are very dependable. Also its under a freakin warranty too....something I can't get on my L92.

So let me clarify my question. What makes the genuine Callies crank (NOT Compstar) worth 2400 when a $900 Eagle one will do the same thing? I'm looking for justification for paying such a huge difference in price. I have not made up my mind yet. I'm looking for input from those with experience, to assist in my decision.

 

I don't know where everyone is getting the idea that Eagle is forged here. It's an overseas forging, just like the Callies Compstar and Scat. They're all finish machined in the states. Law allows a product to be labeled as "Made in USA" if a certain percentage of the work is done here. Callies has the best machine work, Scat is second and Eagle third. The Eagles tend to have more problems with out-of-round journals than the others, so what looks less expensive up front may actually end up costing more.
The best way to pick a crank is to call a reputable shop that builds engines. Ask the guy that balances the rotating assemblies and the guy(s) that do the blueprint work. They're the best source of info on the best bang for the buck. My guy says Callies, then Scat, the Eagle. Eagle used to have a lot of quality control issues (a few years back) but they have mostly been resolved. As long as you're not going to spray it hard or boost it, there's probably not enough difference to worry about. If the Eagle is cheap enough to be able to afford to have it turned to get everything spot-on and you feel comfortable with it, that might be the way to go. Not every Eagle needs work, you might get lucky and get a good one which would be money saved.

 

Easy man, I wasn't making an attack on you. So, let's chill and go over this.

I was talking about the Compstar, which is why I mentioned it was forged overseas. And, like your sportbike, the the Compstar has been "race proven."

Seriously, I was only answering your questions. I couldn't care less what you spend your money on because I'm not trying to sell you anything. I was just letting you know why I went with the Callies Compstar for my build. I didn't get the $2400 crank. If I was going to spend that kind of money I would have probably have gone with the Lunati. Why? Because I really trust that name. I've used Lunati products in the past and have liked the quality.

I've built a few SBC engines using Eagle and have always been satisfied with what I got. For my LSX build, however, I wanted a little more. Eagle cranks don't come as nicely finished as Callies (even the Compstar), at least in LS cranks.

With your build, you'll likely be fine with an Eagle crank. I was under the assumption you were asking what other people were running and why. That's what I originally posted. When everyone else started telling you the same thing and you postured against the Compstar because of where it is forged, that's when I realized you had obvious prejudices on this topic already, and wondered why you bothered to ask.

Seriously, spend your money with who you want on what you want. It makes no difference to me. I would hate for you to feel that you got an inferior part becuase of something I said. But, I would hate it more if you indeed got an inferior part because of something I didn't say. In the end, the money, and the decision, is yours.

By the way, the Japenese sure make some nice bikes don't they?

 

I have used the Lunati cfrankshafts. We have teasted and been on the dyno with several configurations with decent power. They hold up very well.

They are good guys to work with also.

Lunati is the Best! Most times you get what you pay for.

 

I was wondering if anybody was going to mention Lunati
