How do I know I am looking at an M52B28 motor?

More importantly, I am after the crank so it is important for me to make sure it's the 84mm one.

The things I know .. motor is out of a car and seller has no idea what car it came out of. It was bought to repair a motor in his E39 98 528i.

The stamps I can see ...
Engine block has a 1748933 as well as a symbol (that looks like an OPEL logo sideways) with an 84 following it.

The crank has a part number stamp on it with 1714481.

I thought there was a place on the crank that states the stroke. I am building an M20 stroker here and don't want to be buying stuff I won't be using.

The crank should have a blueish color to it. That's how you know you're looking at the forged 2.8L crank.

I am not buying a motor ... just a crank.

The thing will have to go to a machine shop anyway and to top it all off ... it's cheap! Like I mean, really cheap.

This is suppose to be a budget build ... if I was going to throw mad money on it, it would have an M30.

Well you know that the stroke is supposed to be 84mm... so measure it.
Take it to a machine shop and put it on a set of v-blocks and use a height gage to measure the distance between centers on journals that are 180 degrees apart. You should also get a the journals measured as well to see what kind of shape they are in.

After sending the crank to a machine shop, I get the bad news ... it's a 75mm crank! Not the 84 I am after!!!

Just wondering how a block out of a 97 528i has a crank out of a 325/525! Based on part numbers alone after cross checking with RealOEM and a dealer parts guy that's what I found out.

Half-ass way to do a low compression build
