Molnar cranks, Eagle, Scat, and several others are ALL from China. And I would guess from the same supplier. So just take your pick.
From the one's I've seen, the finish machining differs from brand to brand, even though they are all very similar (same?) forgings from overseas.
I've done engines w/ Scat, Callies cheaper line Comp Star series, K1, and Molnar products and they needed nothing but balancing to be used.
Eagle, on the other hand, needs some machining before being installed.
I've never used any of 440 source's bottom end components.
I feel better buying something new that doesn't need to be "rebuilt" first.
