Which manufacturer do you trust ? What experiences have you had? What was the build, dyno numbers, power adders (if any) and how long did it last you?

If money not an issue then stay away from Eagle.
The other 3 are great companies, callies and compstar are one of the best you can get.

Well I wouldn't say its super bad, I can't say from personal experience but when I was doing my research on forged internals I concluded that I would stay away. I have heard a lot of horror stories but it seems like their forged 4340 was decent.
No matter who you get make sure its 4340. Maybe look into scat? their prices are about the same with Eagle.

Compstar is a division of Callies.

i've had very good luck with scat for cranks & rods over the years.i used a eagle 4340 crank on a mustang gt before in the neck sheared off on only 14lb's of boost in took out hood-rad-front a/c coil.so i'm sticking with scat

Eagle is hit or miss. Like forest said life is like a box of chocolates you never know whach ya gona get. That is eagle in a nut shell. Some people use and abuse them with no problem and others build a rock sold street engine and they break. Engine work needs to be done right the first time not oh were sorry we sold you a hot steaming pile of crap, we'll send you another setup but you have to buy a new block, heads, valves and what ever else it takes out with it. Not worth the chance. As much as I like working on my car, I don't like spending money on something I already did once. I like to move forward.
