The thing with Eagle is a QC issues from taper on journals to the cranks breaking behind number two main bearing.Some right out the box needed to be machined 10/10 to make them right.
$200 to $300 can and does make a huge difference when buying parts like that.I am a huge fan of Howards built here and machined here. It's not so much where it is built,but a bigger bang for the money spent. So if a guy is building a engine and is short of that amount,I suggest he saves alittle more and that will come back to him ten fold over time.
