Callies Vs Cola Vs Eagle
Callies Vs Cola Vs Eagle I would like someone to explain the technical reason why one would hold up to more HP than the other given I belive they are all forged from the same raw material
I am told the Eagle is good to around 900HP, I find that strange since most here think the stock crank will handle that or a little more.
Katech has a pretty good deal on Cola's but I believe they are saying the same thing....good to around 900 HP
Now what about the Callies racemaster?? is it that much superior to the other two to warrant the extra $$
trying to spec out my new motor....need input!

You need to find out where the crank was actually forged at. Most 4340 cranks that are still made in usa are made at Louisville Forge and are made from a really strong/durable US made 4340 alloy. I believe callies and cola both use them. Eagle/scat and others I am fairly sure come from China which still use an alloy that qualifies as 4340 but is not as good as the US stuff. The rest is machining (tolerances), heat treating, and counterweight design (ease of balancing). I cannot comment on those with Ls-1's because I have not worked with them to know for sure. There is a difference between US 4340 and chinese.IMO! The callies stuff I've seen SBC-BBC was close to dead nuts in terms of sizing and was usually easier to balance.The cola was not bad.Hope this helps.

Let's not forget Crower (or Oliver, HTC).
Callies also uses induction hardening.
I you are really building an engine for an application you will use pistons, rods, and pins for a specific HP/RPM range. They will be as light as necessary for that application. The crank should be the least weight to balance that load and HP/RPM requirements.
The use major US manufacturers (Callies, Crower) can make a custom crank for those specs.

I was wondering about the China Vs US steel factor, you usually do get what you pay for, just trying to figure the difference in cost assuming the same forging material.

We have a stockpile of them. They're very reasonably priced.
The main thing about Eagle is its not ready to go in an engine straight outta the box, it has to be tweaked here and there on the tolerances. Its priced very well but the cost doesnt end when you buy the product- still though its cheaper after the tweakin is done. I love their 383 kits for the LS1 and will continue to use em but thats because I know whats involved in using their stuff successfully.
I have Custom Nitrous Diamond Pistons, Lunati Pro Billet Rods (1200hp) and a Callies Crank in my 408.. I did alot of research on pistons, rods, and cranks for the LS1's.. I believe that the Callies Crank is the best of the best and the Lunati rods are hands down the strongest steel rod out there without going to an aluminum piece.
Like Bo said.. The Eagle cranks are priced nicely, but their is a little work left to be done when it comes to balancing them from what a few major engine builders have told me. So keep that in mind. But, I doubt you would ever break the Eagle crank with 7-800rwhp if it is "tweaked" correctly..
Diamond can custom make you a piston to work with your setup.. They are very nice pistons and they will hold!

Also starting to see references (Scat Enterprises)to EN30B material which is supposedly stronger than the 4340
What are you after in a forged crank? You are probably after strength, right? Now try to find someone who has actually broken an Eagle crank and ask them the conditons. I'm one of many people running an Eagle in my 402. Now I'm not making anything close to 900 HP and I never anticipate that thing coming apart. Now ask yourself what you could do with the $1000 you just saved. Lots of good pointers in the post for you to follow up on. Choose your goals and consider your budget. Building a 1200 HP engine is no joke, consider all the costs of your "goal" engine and remember that it's only as strong as the weakest link. And if you change you mind at some point and want to get rid of some components remember that its easier to get rid of higher quality parts than cheaper ones. Good luck
