forged crank

Post  72mach1 on January 8th 2014, 8:35 pm

Is there any real difference between the off shore forged cranks, I was looking at eagle and scat stuff. I'm only going to be making about 6-700 hp and figured I did not need to go to a billet crank from bryant or callies to support this kinda power. I going to be using a 4bolt CJ block for this build.

At that power level, any of them will be just fine as long as bearing clearances and all other assembly details are correct. You might check with Adney at Performance Crankshaft for his preference and prepped packages.

Lunati are getting pretty good reviews, and they are in the same price bracket.

You might want to look at the thread tittled "4.5 Scat Crank" if you have not in this forum. It's 4 pages in this section, and has alot of good info, on various brands of crankshafts, includeing Scat. If you allready have, nevermind, thought you might have missed it.

I had not seen it, thanks for the info.

I have been talking to some other people and they are recommending the lunati forged cranks as anther good choice for a lower HP build.

How much money you are willing to spend will have a large impact upon the final choice.

I don't really have a set price, I want to buy quality parts to fit my build. The main reason I asked cause I had been told in the past that all the forgings came out of the same foundry but I have found out that is not the case.

The crankshaft and block are the foundation of the engine, in my mind. I would start with the best you can afford, and Randy kind of made that point, at least I kind of took it that way. You can overbuild I guess, but it gives a cushion for error, and room to upgrade in HP later. By the way 429 SCJ usually got the 4 bolt mains, and are getting harder to come by. May want to figure this in with your decision, just a thought.

I like to overbuild stuff don't get me wrong but just because I can afford a $3000 billet crank does not mean I need one. An offshore forged crank and my CJ block should easily support the 6-700 NA HP Im looking to make in my bracket car. I was trying to get a feel for which forged crank was the best from some real world experience. It looks like the Eagle is out and its between the Scat, Lunati or possibly Ohio crank but still have not heard on which one might be better and why.


I have some Cleveland bearing spacers coming if I don't like they looks of them I will be buy a new rotating assembly and would like to have my ducks in a row.

I am not going to make to many statements on cranksfafts except from personal experience if possiable. Alot of the forum is building on others knowledge and experience, as I am sure you know. With that out of the way, Ohio Crank was mentioned in another thread, here, and the concensis, seemed to be, was that they needed more machining for proper clearances, at least that was my take, as to why they where cheaper, amoung few other issue's. Might want to locate that thread here in the engine section, it was about 4.6" Ohio cranks and a clearance sale. Like I said, ths is what I read, so it is second hand knowledge. I have run( Beat the Sh$T out of it, big shot's of Nitrous 7,000 Rpm plus) a Scat forged crank in a SBC, but it was purchased about 12-14 years ago, with no problems. I to wonder about it orgins and quality now, when the word off shore is mentioned, and if this one was imported.  I only mentioned the money part, even though you don't need a $3000.00 billet crankshaft, you may wan't to spend a little extra for peace of mind, and it doe's not imply any guarantee's then either.

At 6-700 NA HP, you could probably run a cast crank. An offshore forged will be overkill. A $3000.00 billet would be a waste.

My last post was ment to read "a little extra money on a quality forged crankshaft", did not mean to imply he needed a billet at all. It was bad grammer on my part, and I did not want to edit the post. And yes a forged crankshaft is overkill, but he was asking about forged crankshafts in the post, and specific brands that he was considering, Eagle , Scat, and Ohio. He has a nice and rare 4 bolt CJ/SCJ block and I mentioned spending a little extra for quality, peace of mind, and resale value, that's all. He ruled out the Eagle, and I told him about my experience with A Scat and what was mentioned about Ohio Crank, in another thread. Sorry if there was any confusion.

supervel45 I told him about my experience with A Scat and what was mentioned about Ohio Crank, .
 
 
 
the Question is Just what is your experience? you and Jim have to be either the smartest guys in the world or just post Whores...      the guy could either get him and Eagle, Scat or Lunati and be fine as long as it is forged. A stock Factory Crank is a tough piece.

Thanks for all the info, I know a offshore forged crank can be a sore subject, but from what I have been told is that there is no American company that sells an American made forged crank unless you step up to a billet. Is this correct or have I been misled? A billet is way overkill that why I asked specifically about offshore forged stuff.

Ford 460 Magnum Crankshaft
Posted by Matt on Friday, November 22, 2013  
 
Callies now offers high quality domestically produced Magnum crankshafts for the Ford 460 – 429 engine families.  These crankshafts are machined from high quality forgings that are heat-treated and metalurgically certified at our facility. Magnum Ford 460’s are counterweighted to balance bob weights up to 2400 grams without the use of heavy metal.  We are confident in the ability of our Magnum 460’s to easily withstand the rigors of a 2,000 HP engine.
 
Standard Features
* Average Weight – 78 pounds for a 4.750” stroke
* Gun Drilled Mains
* All Rod Journals Lightened – 2.200” Diameter
* Stroke Availability 4.150”, 4.300”, 4.500”, 4.750”
* Single 3/16 (Align- Ease) Keyway with Lead in Witness Mark
* Short Damper Fit (High Performance Style)
* Heat Treatment = Perma Case Deep Nitride Options
* Full Internal Balance
*
If domestically produced, counts this is one source, it seems. Not Billet, But not the brands you mentioned either. Not stock stroke either. Were the forging imported, hard to say the way it is worded. Read the part about heat treating and machining, a couple of times. It is not clear where the forgings come from. This came off the Callies Website News Page.

I also use a rare SCJ Block 4 bolt w/ CJ cast into the valley. I run a Eagle Forged 4.5 crank I bought when they first came out and I got a nice one. Eagle got a bad rap because there was a shipment of early cranks that got loose that were not the best looking forgings and many rejected them on the looks. my car runs very fast and the Eagle has performed just fine.

I think the question had changed to if there are any american made (forged in America) forged cranks left, not that the offshore cranks are bad. The poster was trying to get the best forged crank, and did not want or need a billet is all. There was a sister thread to this one also.

To clear up any confusion, the Callies SBF forgings are hammered out in Kentucky. The Callies BBF forgings are coming from Sumitomo Heavy Industries in Japan, who are also the manufacturer of Sumitomo forging presses. They are being made from Japanese steel. This info comes from an employee of Callies.

For anyone who is unfamiliar, the Japanese take their steel very seriously and it is usually high grade stuff.

thanks for the info Paul. Yea the question kinda morphed but still was looking for the best offshore crank because for my build I do not think I need anymore than that. Looks like my question should have been who has the best Machine work on an off shore crank.

I got my bearing spacers and will be deciding weather I throw away my stuff and starting over this weekend

I used to get some knife blade blanks from Japan when I was into knifemaking. The steel was top quality for sure back then.

Were the spacers the 351W deals?

opening this thread back up for more questions. If the offshore forgings are all about the same, why is it the Lunati, Ohio, and Eagle 4340 4.5 cranks sell for around $700-800, while the Scat sells for $1100-1500? Is there really a difference with the Scat that makes it worth more? Looking at the "you get what you pay for" thought process.
