ya im planning on buying a block from them. im just waiting on results from eagle. if they screw me over ill never deal with them again.
my machinist says i shouldnt have any problems getting something out of it so will see.
as for the rods, they are eagle also. what kind of problems are they having? cause we just put a mic on them and there still in spec even after the crank beating.

I've heard of countless rods going through blocks. Not sure what causes it, but even the big engine builders around here (Thunder Racing) don't use them cause of it.

Don't panic over the Eagle stuff. We've used countless crank kits from them, and have never had even one failure. Not cranks or rods. We only use the 4340 stuff.
You're crank was not a 4340 unit. I've seen the cast cranks break. I've seen more SCAT broken cranks than any other single manufacturer. I've seen the Eagle cast cranks break, pretty much just like yours.
Also, Eagle stuff is forged in China, but I'm pretty sure it's machined here. Callies CompStar line is forged in China as well. So, you can't just point fingers at Eagle for using Chinese stuff.
Also, to the OP, if Eagle does help you out, consider it a good will gesture. It is a performance motor, and a performance part. And not a top shelf part at that. There should be NO WARRANTY on that thing. I wouldn't warranty it, but then again, I don't build motors with them either.

yea ive heard bad stuff only about scat really. i built a stroked LT with solid roller twistin to 8 grand on an eagle bottom end and it sees a ton a time above 4 grand.

Well anything with the forged 4340 steel would be good.

From what I've heard (and been told by Thunder Racing), the problem with the Eagle rods, is pretty much just the H-beams. Don't know why though.

To me it just seemed like I was creating enough power on the Stock setup to not hurt it. Then when I finally added a Cam, Exhaust ETC and free'd up some more ponies it was more then the casting could hold and snapped it. Although it Never seen a WOT run on the new cam setup in that 40 miles. SO I know it didnt hit any of its power ranges.
As for the eagle rods, So far so good. I dont see any issues with them. I think on a good tune the motor should be solid this go around. I just wish they could hurry LOL!!
I am going back with a 4340 forged crank this time regardless, Im also going to back all my other mods up on a 100Shot for the track.
Just to clear it all up, This is not my car, LOL sorry I keep referring it is, I use to own it about 8 months ago, When I first built the motor I sold it to my good buddy, I do all the maintenace and all the mods to it tho, SO I know what it has and don't. Its just been in my garage so much lately it seems like mine again HAHA!!
But we are building it as a full street car with an occassional track weekend, Thats when we are going to run the 100shot. We possibly might up it to 200Shot eventually, But I have never ran Nitrous and personally don't like it. But There is a first for everything.
My buddy the owner wants to build it to beat my 240sx! Which I have embarrassed him several times at the track before.
We did a Street race night at the track here a few months back and I Spotted him 5 cars in the 1/8th and I came around him like he was settin still at the 550' mark. LOL

I'd go back and check the HP rating of that crank too. I'll betcha it's not rated for near what you think it is. I wanna say the 4340 ones are rated at like 600 hp or something. Very conservative for what they are. I would think the cast steel would be rated much lower.
Edit: Just went and looked at their site, and they don't even list ratings. If you ask them, I pretty much guarantee the ratings are much lower than you think. Very conservative.

well i just heard from eagle today. they considered tthe crank faulty and gave us full credit for a new one.
they are sending us a new 4340 forged crank along with a new set of bearings. there was a 400$ price difference we still had to pay.

Well I dont mind the extra work for the swap. I Just like the LT1s better as well. and too many pple are using LS1s. I want to be a little bit on the sleeper side.
