Wow makes me happy I stuck with a stock refinished crank for my forged 348 instead of getting a forged 383 or 408 using a eagle crank. This car is taking long enough as is dont need any more problems.

I certainly hope the get their act together soon.
Todd is right customers shouldn't have to be doing R&D for Eagle. I would send them your bill for clearancing the crank and re-balancing.

Funny...there was a thread a week or so ago that someone claimed there were no issues and handly any balancing...could the cranks be that different of was someone looking at boxes and doing assembly in their mind? Anyone actually hav the 4" stoker crank installed and running?

Well the Eagle stuff SHOULD clear a 6.100 rod according to them but still you always mock stuff up FIRST before doing ANY machine work. You also had to add metal and do extra machine work on many of the other cranks as well initially with the LS1 stuff. The piston manufacturer is also required to check this stuff since a lot of the time the problem is with them too.
On the balancing they tell you what bobweight it goes neutral at so if you don't know that on either you can't really say anything about Eagle there.
I just noticed that there is now a Nick D'Agostino and a Nick Agostino. I was getting them mixed up!

Eagle 6.125 rods, Eagle 4-inch crank, Diamond 11519 pistons (4" stroke and flat top with reliefs).
Tuff - Actually all the stuff from Eagle and Lunati are forged in China. I just found that out myself this past weekend. China (Taiwan) is the scrap metal capital of the world.

Good to hear Eagle is gonna cover extra shop work. Just curious, is the Diamond piston "recommended" by Eagle? Or is there no specified part compatibility until now? I was also very close to buying a kit for my project 5.3 to 5.7 engine. I hear the "get what you pay for" from others but dang, $4000 Lunati vs $2300 Eagle. Unless the machine shop comes back for $1700 in labor costs you gotta wonder what Lunati is doing special with their kit. Unless they happen to drop the price of their kit now that they have some competition? One poor guy posted his Lunati kit on Ebay right next to another shop selling the new Eagle kit. He is now piecing out his Lunati parts.

Kurt....bob weight for the 408 NA motor will be about 930 and the weight for the boost 408 will be about 915-920. The up side to all of this is that these motors will have awesome throttle response and extra power due to 150-thousandths being removed from the counterweights

Todd, are you using some super space age material for your rotating assembly?? 903 grams is just over what half of your bobweight should be. Do some recalculating on that or let me know if I am missing something here. It might just be me, but I have never had a bobweight that light before. Our aluminum rod LS1's were still in the 1600 gram range.
