Hi all, I checked my VIN # and it shows that I have a B28F engine in my 1987 760 GLE. But I thought that 1987 760s had B280F. (in North America) Which is the better engine, any huge differences? hp? Either way, its running super sweet, I just want to know which engine I really do have for my own records. I assume they both look the same. Cheers.
