Depends on what you are looking for cheap or quality? You can get a cheap setup from Eagle, but they will require some more machining to fit and balance properly. If you want high quality parts look at for cranks - Callies, Lunati; for rod - Manley, Callies, Lunati; for pistons - Diamond or Mahle.

I went with Eagle through a reputable company that I am not sure is a sponsor. AFR uses them so that can't be that bad. They have also competed in a few engine master challanges. With it balanced with Diamond pistons it was $2,350 to my door. They have used this assembly up to 1,000hp. I will PM you with the name of the company.

Callies and Lunati may be better parts, but I personally have used probly at least 25 eagle rotators in the past year and they all seemed to balance out well and install without any problems. Alot of 402/408's and alot of 383's.

Are you saying that JE pistons are not quality - that happens to be the pistons that W2W generally uses. Quality is not based on dollars spent, but rather on the reliability of the parts that are being evaluated. Give us some proof on what you consider to be quality vs cheap - talk is cheap and so is bullshit!
As for reliabiliy a decently forged steel crank will have the same strenght as the more expensive one. There is not many things to change in the process of forging steel except the mixture of the steel components. A 4340 steel has to meet certain criteria for strength to be considered as that alloy. That will make the reliability the same since all 4340 steel should fall between a range of characteristics for that metal.
Finally, I would ask why do you come out here with that attitude? You could have kindly asked me to explain my reasonings instead of essentially calling me a liar. It seems that you are more of a Troll when you come across acting like you did.

Quality in most cases does cost more and thus you will spend more money on the quality parts. A Callies crank is a perfect example when compared to an Eagle crank. Eagle's tolerance that I have seen in engines is no were near the closer tolerances of Callies cranks. The Eagle stuff works great in old SBC applications because the tolerances are not so exact. When you get into LS based applications things are much more precise. I have seen at least two engines using Eagle stuff that had to have more material taken off the rotating assembly to properly clear the block and balance. This means you put more work in making those products properly balance. This is due to the difference in manufacturing of these products and some of the extra work you pay for when you purchase a crank from Callies or Lunati.

I fail to see the term liar used anywhere in my previous post. You are not a liar or a metallurgist for that matter.
When one refers to a manufactured product as being cheap, that implies that the part or parts are not reliabe and will fail in the field.
Guys out there - please grade your Eagle 383 stroker kit - is it a peice of cheap junk or a good reliable product?

4340 may refer to a chemical analysis of the steel, but it is not an exact science only a range of certain chemical contents. A perfect example would be steel content between 38-43%. These contents when place together also have certain physical characteristics for the metal.
I am glad to hear you say I am not a liar, but in making comments like talk is cheap it is assumed that is what you mean.
Nothing in cheap refers to something not being reliable. Often one can offer the same product to do the same duty and cycle for a cheaper price by using different materials or eliminating certain actions to create a better cost. In Eagle's case they often create a product with loose tolerances that reduce the requirement for additional machining. While this process reduces the overall cost of the item it does occasionally create the need for more work to be done on their products to achieve a desired result.
David you may also want to use spell check there are a few mistakes in the last post you made.

The production of any given steel grade is an exact sicence - with a pre-designated range for the various chemical eliments within that grade of steel. If the chemistry of the heat falls within the set specification, then you can be assured that the desired mechanical properties can be obtained when the material is properly processed in the solidified state.
Your original post stated "cheap or quality" when referring to the products that you choose to evaluate. In my book cheap means a product of lesser value and not a good choice when purchasing said products.

When you look at a grade of steel it is not always the case of what temp it was heated at. If you see a number for aluminum that is a 500 series or maybe even a 600 series, that is when you know it has been tempered, as far as steel, when you see a four didgit number that is usually the makeup of at least two elaments, ie Iron and Stainless. and it usually is made up of more than just two. Kinda like a 70 to 25 percent leaving 5% of none purity metal in it. Now if you see a three didget number like 300 series stainless, or 400 series stainless than that is when that curtian type of steel was rolled at a curtian Temp, to make it either a stonger or more machinable metal.
I am sorry for my spelling cause I am not a Lit expert, just a machinist. And I am not on here to take sides, just looking at it from a different point of view.

As for the whole cheap vs quality it is your personal opinion. All of this started because your opinion differed from mine and you attacked me because of it. Next time I suggest you post your opinion as well, but you do not need to direct it at others in the way you did with me.
