Nabit,
I wish you well and hope this works for you.
There is no way possible I would consider using unknown components in my own engine or in a customer engine.
At least the Eagle, Scat, and Cat are established with their own reputations now.
You did mention that the crank is a cast crank? To me that sounds scarey but if it is for low horsepower it may be ok. That does start me wondering though. Cast 4.250 crank? There is not many around. Maybe that is a clue about who Hawk really is.
I do wonder about the product choice of name too. Hawk - Eagle. Hmm' would be easy enough to have the same logo. Wonder if this is an Eagle underground Buyer/Supplier?
Maybe it is good parts that are sold in blemish sales. I have nothing against the blemish stuff.
