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?

The Eagle and Callies Compstar 4.100s work great and are no different than the big money stuff you are talking about for a street engine. They just weigh more. For the money they are a much better value but again you have to know what you are doing when you start doing rotating assemblies with the bigger strokes and the shorter cylinders of these OEM blocks.
I agree with this as the stock cylinder is very short so all the ones I do have a custom piston that works in this situation fine but I do not do big NOS or turbo engines or blower deals with the shorter cylinder and the bigger than 4.000 cranks unless it's very low boost or NOS. In NA form they work absolutely fine. The ring stacks you can run in these deals are totally adequate for normal NA usage. The other problems people have with these longer stroke engines are solely from their lack of understanding of how to build them.

We use the Lunati 4.185 crank sometimes too in some random builds and their cranks are very nice overall. You always have to check anything out as we've had some issues with every crank company. Again it depends and comes down to the last person that sees that crank before it goes into the engine.

Callies Dragon Slayer, Magnum and Magnum XL cranks are forged right here in Lancing, Michigan then shipped to Fostoria, Ohio for machining and heat treat. Give Brook Piper, (Callies Rep) a call and he’ll give you the details.

Erik, glad you posted. Could you email me the tracking #'s for the pistons and crank you sent me? The wife says she hasn't seen them show up yet. I'm sure shipping is a little slower during the holidays.
I've been stationed somewhere else and don't have access to the email address I normally talk to you from, can you email me at my yahoo account? toneloc60@yahoo.com
It's been a pleasure working with you. Thanks.

I am waiting on the special oil rings and then it is on it's way to you. They sent me the wrong ones. Hope you have a great Christmas over there and be safe!

It depends on your tune up and the rings used and how much power the engine is making already etc. On a normal deal I think you could still run 150 easy. There is just much less room for error with the thinner ring lands of course.

10 LS Engine Myths That Refuse to Die
Verdad Gallardo I will be running Total Seals Gapless top rings withe Napier second.The LS7 block I have will be dry sleeved which I believe has a little longer sleave? I'm reusing most of my stuff from my 427 like the 6.125 rods and will be getting a custom Wiseco piston. Would there be a better choice between running a 4.100 crank versus a 4.125?Traver
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.
Callies Dragonslayer is the most affordable crankshaft you will find USA made.
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.
We use a custom callies 3.75" stroke in our shop car.
The Magnum XL goes another step with machine work, even lighter and is full balanced by callies, they arn't balanced by drilling, the counterweights are shaved to match bobweight. Your high end engine builders believe drilling the counterweights causes windage.

No you are fine with either one although again shorter is better for power adder and piston compression height if you need it. The rest depends on the piston.
I wouldn't run any gapless rings but that's up to you.

All the Callies cranks we have used have been great as well and all the regular Callies from the Dragonslayer and up like the Magnum and Magnum XL etc. are American made. The Compstars are forged overseas but the rest of the finish work is done at Callies. They are also very good parts and extremely well machined by Callies.
Can you elaborate on not using gapless rings?Is this from experience or hearsay?I have been told they have great sealing charactaristics and very little leak down %'s.Also are very durable and create more compression there for added horsepower?Traver

Do searches. It's common knowledge. I love Total Seal rings and use them a LOT but not the gapless variety and especially not on any street engine with no vacuum pump. Everyone's been through that on this board including many sponsors to the left. There's a reason there's not a gapless ring to be found on any car on the planet. Believe me it's not because they are all "not in the know!"
I have searched this repeatedly and even talked to Total Seal reps at Sema and on the phone.I heard exactly what you've heard about them.............but that was quite awhile ago.I guess over the last 2 years they have changed the desighn to a stainless ring that's much better then what they had before.Traver...........I would hate to be a guenie pig though?!
Eagle is made in China, not thats bad, provided they strictly scrutanize their manufacturing like compstar does.
Callies Dragonslayer is the most affordable crankshaft you will find USA made.
Not entirely true, the callies Magnum can be made in any stroke from 2.600 -4.300, they are lighter from gun drilling approx 48lbs.
We use a custom callies 3.75" stroke in our shop car.
The Magnum XL goes another step with machine work, even lighter and is full balanced by callies, they arn't balanced by drilling, the counterweights are shaved to match bobweight. Your high end engine builders believe drilling the counterweights causes windage.

Where is the best places (sponsor) to get the crank from? (ie who has the best price, since i've seen $100+ differences for the same part). The engine shop that I'm looking at can't get them cheaper than I can. Is it just me, or don't most engine shops get these internal parts for less than just the 'joe customer'?
Their is (2) companies I know of with crankshafts contracts in China I would stay away from, an eagle crankshaft is 100X better and easier to balance then these scrap jobs. None of these companies have been mentioned here.
I have seen eagle cranks easily take 1100-1200 flywheel hp without a problem. This was not just one motor, multiple times eagle cranks have shown they can hold the same power as a callies dragonslayer without paying the extra 400-500 bucks. Since you are going with a 4.100 stroke motor and you can't really add power adders to that length stroke, IMO an eagle would do great for your setup. If you were looking at a setup that was 1100+ hp I would most definitely reccomend upgrading to something like the callies dragonslayer or similar, but seeing as you are not it would be unnecessary to go with an upgraded crank like that. Just my .02, and good luck with your build.

So is it the general consensus that the Callies Compstar is superior in quality and machining to the Eagle? Also I did not know the Eagle was forged overseas. Interesting.
