Connecting rod length

Does anyone know what is the connecting rod length of the BMW S70/2? Or the r/l ratio, that is the ratio of crankshaft offset to connecting rod length?

Not off the top of my head, let me see what I can find -Is there any reason why you need this info?

Not really. Its just that I was analysing a picture of the engine disassembled and I repaired that the connecting rods looked awfully short. And I've read that if the radius of crankshaft divided by conrod length is bigger than 0.3, the engine runs harsh on high revs, what couldn't be the case in a car like the McLaren F1. Since the crankshaft offset is half the stroke, I just needed the connecting rod length to know the r/l ratio.
