I've seen that too, in fact the guy that did machine work for me had one in a 11.00/10.90 A body with an automatic and it broke the same way.

Just another example of people not following the recommended HP ratings for these cranks. A 3000lb A body with a 200lb drive will go 11.40 with a 500HP engine.
In other words, your machinist was making around 540-550HP to run 10.9's with the cast crank. Is it any wonder it failed? Clearly with that type of HP the motor should have had a forged crank.

It doesn't take 500hp to run 10.90's @3200lbs. I tried to use an eagle cast crank in my daily driver truck,but in 10 minutes after it showed up I had in back in the box for return. I was not able to save my buddy as he used this crank for almost 2 seasons,running 11.00 @ 3200lbs then it came apart and destroyed a lot more than the crankshaft. Good luck.

I will agree to disagree, in my opinion it takes all of 500+ horsepower to run 10.90's in a 3200lbs door car and the need for a forged crank is obvious in such a fast car. If the friend got two yrs. out of the deal I would say he did pretty good considering the crank is on the ragged edge of its recommeded range.

Thats the second one i saw that broke the snout. After examining the one I had, I thought the weak point was the rear arm/journal cross section especially with all 8 cylinders twisting it.

I will agree to disagree. It does not take a forged crank to withstand that output. Just a factory cast crank or a cast MP/Scat crank and you'll have far better odds of a reliable engine,rather than a potential disaster. The engine in the duster was less than 500 hp(yes, it was on the dyno),so give me some idea how long that crank might last @ 450hp,475hp,etc I'd love to know the answer.I'll just keep putting better cranks in my builds and sleep better.

Not all dyno's are created equal, just ask Hughes. At 450HP the eagle cranks are lasting a very long time, 7+ yrs. which is a long time in the life of most street strip rides.
In fact I just got 7 yrs. out of a 360 which had two cylinders cracked. Was it the blocks falt these cyls cracked? Who knows, however it didn't help that I overheated it a yr. ago when it started leaking fluid. So which came first the crack, or the overheating which likely led to the cracks?
What did I put back in? Another 360 because they make great drag motors with or without a stroker crank..

just love that duster

Yep, I'll call Hughes in the morning so that I can be truly informed.

I will agree with you on this, Hughes is not all they are "cracked" up to be..

Interesting to note Mancini racing sell three different brands of cranks including cast eagles.
Things that make you go hummm? If eagle cast cranks were such an issue why would one of the top Mopar houses carry this product?
When you call the Hemi hot line they have no ill feelings about anyone using cast eagle cranks and have no mass reports of eagle crank failures?
To me this whole post was likely started by a few ill informed Scat fans.
According to my local speed shop it is Scat that is having the quality control issues, not Eagle.

Latest update, our 408 with the eagle cast crank went 11.93 @ 111.4 in our 3600lb b-body satellite today.
Boy am I happy..

And of course when it breaks you'll update us on that as well right?

---

We can hope he does. I'll make a deal with him,I'll report back when the stock 360 cast crank breaks,it's been 100,000 street miles and makes 10 second passes without a second thought @ 3600lbs. We have hundreds of passes on this junk so you better get busy.
