Both Scat and Eagle are forged over seas and machined here in the states.
Scat has been on the scene along time, used to run that stuff in my VW.
I have forged Eagle internals in my BBC - everything was good, right out the box.
I don't think you'd go wrong with either, so long as you double check everything real good before assembly and get a good spin job.
Goodluck, Cp
