Callies crank vs. Eagle crank
When comparing Callies Racemaster to Eagle, there's a $600 difference. When comparing the new Callies crankshaft, the Dragonslayer, there's a $300 difference. I believe the Racemaster is being discontinued and the Dragonslayer is taking its place. Anyhow, I was just wondering what the difference is between the 2. Is it just the name? Does the Callies support more power than the Eagle? I'm having a hard time deciding between the 2. The connecting rods are all about the same price from one brand to another, so I'll probably just go with a set of Compstars (Callies) for rods.

Foreign or domestic? That's were the diffrence lies. Chinese steel is cheaper and more brittle, wearas american steel is a better quality, thus providing a better crank. Balancing is also easier with the Callies. Eagles usaully takes a good bit of heavy metal and more time to balance, thus costing more to bablance. If you save $300 on the crank, you may spend $200 of that back on extra balancing charges. The Callies will be the stronger crank, but you have to think if you'll ever even get to the limits of the Eagle. If the diffrence is only $300, then I would go with Callies no doubt.

I thought these cranks came balanced already?
There is only a $300 difference between the new Callies cranks (Dragonslayer) and the Eagles. I actually found the Eagle cranks even cheaper at Texas Speed & Performance, which would put it at a $403 difference.

We have had nothing but good results using the Eagle crankshafts. So for us we have to ask, why change something when what your using already works fine?
Off the top of my head we have had an eagle crank in an 850rwhp nitrous car, 998rwhp twin turbo C6 and a 1028rwhp twin turbo C5 (Using off the shelf Diamond pistons by the way). I have never personally seen an eagle crank fail.

I guess in the end, its up to you/me what to go with as its been proven that the Eagle crank will hold up in high horsepower applications. I'm certainly not going to making anywhere close to 1000 hp. I hope to make around 550 rwhp, but who knows.
I didn't realize price in balancing varied. So if it took the Eagle more to balance, costing me more money, then I would probably be better off spending more up front on the Callies crank. Do cranks not come already balanced?

Cranks are balanced with flywheel and balancer attached. Also all your piston/rod assemblys are weighed, then bob weights are attached to the rod journals, simulating their weight, then the crank is balanced.

Correct, every crank should be balanced to match the pistons & rods it is being assembled with. Lighter pistons & rods require more material to be removed from the couterweights due to the lighter bob weight. While balancing is not necessary for a street engine, most race engine builders balance the rotating assembly for longevity.

The Callies is a nicer piece, however, the Eagle still gets the job done perfectly.. It's kinda like comparing a Ferrari to a Lamborghini. Both are great. The Lamborghini is more expensive, but since you're not going over 100, who cares?

Your new motor can also be compared to hot poon... mmmmmmmmmmmm...

I know of quite a few guys running blown BBC Marine setups with close to 800hp. They are running 4340 Eagle Cranks and H beams. In our Marine races we hold WOT for over a minute in some cases. That should tell you something right there.
