My machinist has not seen too much Eagle stuff but his only complaint is to check sizes carefully because the finish sizes vary. He had to grind a new crank .002 just to get it to standard.
Once in an engine with clearances set there is very few complaints.
my machinist said that he's seen eagle forged cranks that look like they polished them at the factory and these journals were concave/rounded slightly and had to be turned.even though, i still went with a je,forged eagle h beam 5.4 and forged 3.25 crank.
I've had both and it seems the Eagle 351W stuff is sometimes weird. The SBC and regular 302-347 stuff was fine too but the 351 Windsor stuff was ground too big on the mains and had to be reground. Besides that they seem to be fine.
