Identifying crankshaft

Guys I would not be worried about a Chinese forging. As long as it's a 4340 piece it will be plenty strong. We run a eagle crank as are others that make a ton more power than my junk.

I do not think so, the crank is balanced off the net weight of rotating assembly and each piston/rod would be made to equal others as far as average weight.

If you had planned on reusing bearings/rings then matching bores would matter, but quick hone to each bore and slap it together.

I'm just saying that if someone sold me a "callies" crank that ended up being an eagle I'd be pissed.

But yeah it doesn't look like either.

"TFS" looks like trick flow specialties which was made by cola, which also forged for summit at one time. Either way, it's forged, has chamfered oil holes, and radiused journals. It'll be fine

Thank you for that chris, that's what I was looking for
