Is Eagle Products Over-Rated??

I've been searching for new connecting rods for our Sprint car motor and looking at Summit Racing, it seems that the good named brand manufacturers like Lunati, Howards, Callies, Carrillo, etc. advertise most of their SBC rods from around 650 -900hp but Eagle advertises theirs for 1200hp. I think Eagle is over-rating their products. What do any of you think? I have never owned an Eagle product.

Due to a very long history of bad results of Eagle products,I will never suggest or own anything from them.Your comparison to the other brands is really a apple to oranges.You get what you pay for.

Many years ago I bought a set of eagle rods and a eagle crank for a 350 sbc and they were never put into my engine cause I read to many stories were people had to get there cranks .010 under to get them to spec and also had to have the rods resized in order to get proper spec on them and this is with there cheaper street stuff clear up to there all out racing stuff so I went with scat rods and a scat cranks and they were perfect and right on spec and still running them today and they are about the same price as eagle.

depends, 1200 hp from a turbo is easier on parts than 1200 from 650hp engine and dual happy gas shots.

most sbc are not making 600hp and most likely yours wont either

And most likely you are wrong, guaranteed!! I'm not talking about "most" SBC, this is a high hp, high rpm 400ci motor for our Sprint car.

I know it was a bad comparison but between the different hp ratings and costs, that said something.
But Gary1, I'm interested in your statement of "Due to a very long history of bad results of Eagle products", why was the history such a long one? I would think after 1 maybe 2 bad experiences with a product, you would have changed directions sooner.

I only use Oliver rods in real race car engines.
The quality is impeccable and the price is OK.
For street use, I have used many Eagle and Scat products and had almost no issues, but would choose Scat if I had to choose.

Same here, there were issues with Eagle products years ago, but I've heard they cleaned up their act. I have Eagle forged crank and rods in my 8-71 street motor from seven years ago, it checked out perfect with my machine shop. I have the same parts in it now even after detonating the motor, replacing the pistons. I can't comment on more recent QC.

That said, for a serious race only motor I to would go for the high end proven parts.

This is like opening up a big 'ol can of worms (or discussing who is better-Ford or Chevy?)-

You will get a lot of opinions on this, and I will add mine-

There is little doubt that there was a documented problem with Eagle products Cranks about 5 or so Years ago-most of the concerns were in concentricity of the Crank Journals, but, most all will agree that Eagle has fixed this problem.

Regarding Eagle's 1200 hp number, I believe that number is derived from using their ESP "H" Beam Rods and L19 bolts-I hope we can agree that Rod Bolts are one of the reasons for this rating as L19's are rated up to 270,000 psi (above 8740 and arp2000)-

I am an Eagle user, and, when my Engine Builder first opended the boxes (he is a big Scat fan), he measured them and was very impressed by the Crank and Rods-they balanced easily.

At any rate, my engine isn't a 1200 hp engine (I am running L19's), but it did Dyno at 775.5 hp (and, it didn't blow up!), so I am a happy camper-

Here is a picture of the Rods-



And here is a picture of the Crank in the Block:

I'm not looking at "lowball rods", I was asking a question of the comparison between different manufacturers and your responses prove you know nothing about what I am doing.

Agree with the Olivers, hard to beat

X2! When I think of power close to and above 1000, I think Howards, Carrillo, Compstar, Lentz, Oliver, Pankl not companies that all buy universal Chinese forgings as blanks then finish machine (maybe) and put their name on the product.

Will a good quality Scat rod stand up, if using the proper hardware? Probably, question with this stuff is at what point does the number of stress cycles lead to sufficient fatigue before it fails. And, if it did fail, what is your recourse? What would your down time be and the expense incurred. Oliver may be a safer bet.

The sustained high RPM in oval track racing warrant's the need for a class rod/bolt.In oval track racing the lowest dollar crank we use is Howards Track Smart.You should understand that as a engine builder with clients we sell our rep.Not the highest dollar engines,but certainly not the lowest either.The history with Eagle was aside from being out of spec number 2 crank journal was crack or braking in oval track engines.People will post but they have been using Eagles for yrs,Those folks are not using them as you will be.
