Anybody have any experience with eagle rotating assemblies. I am thinking about a 383 kit. It will be for a mostly street vehicle. are these quality parts and how will they hold up.

Its not an easy question... When compairing cranks and the word"quality" is used..its open for debate. While an Eagle 4340 crank is a decent forged cheap crank, it dosent compare to a Bryant or Callies. Most will tell you that the Scat rotaiting is better quality.
Eagle rods are pretty good. I wasn't impressed with their cast cranks.

I am interested in theri cast crank since this will be a street motor.

In my opinion Scat has shown much better quality control.
It is all I will use for the less expensive cranks.
