I have read it but can't find the answer I'm after can any 327i block be used as there is a few different type

[Grrrmachine]

There's no such thing as a 327i. There's a 325e, which has the BMW official 2.7 engine (M20B27), and there are the three "home-made" 2.7 permutations listed in the link Ben provided. Click on the links in that article and you'll get all your answers - it's been covered dozens of times.

The actual block is identical for the 325i and 325e cars. It's the crank and pistons that create the difference in displacement.

It will be stamped 27 on the small rectangular cast face to the right of the bottom of the dipstick tube.

I thought the deck heigh of the m20b27 was approx 0.5mm shorter than the b25?
