I'm not sure, but depending on how accurate your balancer is, you can see an insane difference if your using a cheaper balancer. Our Hines "Eliminator" balancing system is extremely accurate, the employee I have behind the machine has 30 years experience, and is one of the best in the country hands down. I know its not my balancer.
They are rough balanced on Hines balancers at Eagle!
We've literally spun cranks 10K and they sure don't vibrate!
Maybe you have a calibration issue?

I do not personally like the Eagle crankshafts. At my shop I use a Hines Balancer. Every time we throw a late model Eagle crank to spin, it requires at least 4 pieces of heavy metal. This is a sever problem with cost, and speed of assembly. They can cost up to $700 for the customer easily. Also, the pre balanced assemblies we've received are out 10-20 grams from one end to another.
Scat, and Callies are the only two cranks that I have balanced that do not require extra material. Scat offers a 4.00, 4.125, and 4.250. Their Crankshafts are well worth the money, come with the reluctor pre installed, and heavy metal pre installed as well. The actual pre measured bob weight is about 1850. Most rotating assemblies are less then this.
I think by reading my post you can see what crank I prefer.

Does this mean Callies is bad? NO it just means that the guys heavy NOS BW was higher than what the crank was set up for. The Eagles are roughed to about 1790BW. I have had to weld the holes back up every now and again depending on parts but that's engine building.
I do hope the SCAT LSx crank that I get is a nice one though as I like SCAT for some of their stuff. They used to make LSx cranks with no thrust surface to speak of but I think these new cranks are fixed in that reguard now at least.
I sell and use them all including Lunati as well which also come with heavy metal already.

My Eagle 4.100 crank came with heavy metal already installed from Eagle ,and the machine shop Red Cornetts in SummerSet Ky. i took it to ,to have it balanced said it was real close and only had to remove about 3grams, the cranks has been in the engine for over a year and had a lot of high rpm runs and still going strong

That just depends on your BW as sometimes of course they would and will need heavy metal. I had to add 6 pieces of Heavy Metal to the last 4.000 Dragonslayer I did but it was a 2000g BW and that crank was bought to go only 1750g internal from a vendor on here which is their default BW for that crank.

I know a company that doesn't even rough balance their crankshafts, over 2000g
The counterweights look like swiss cheese when your done. Considering most LS1 combinations end up being 1770g or so.

I wonder if thats where my crank is going to end up using 600g Oliver Speedway 6.125" rods, and a Wiseco 4.125" pistons. Although the crank should already have most of the heavy metal added as it was balanced with the same rods, but different pistons before.

600G is light for an Oliver speedway rod. You should be fine Haans.

Well they have heavy and light and medium weight rods but it's their parabolic I-Beam design that makes them heavier at the big ends as compared to say other rods. They are a good company though and I have never had any problems with them.
