Help! I have a 1973 distributor from my original engine which and I intended on using for my replacement engine. The problem is this new engine has a 1984 head which has high compression piano top pistons mated to a 1974 engine block. From my previous research they say that the distributor/camshaft in the 1980-1984 models of M10 to turn in the opposite direction, thus making the original distributor unusable. I just want to confirm if anybody has had this issue before, what the reason being would be because it does not make a lot of sense. Why would bmw do this? Anyways if that is the case I am looking for a 1980-1984 distributor off an e21 if anyone has one lying around. Any help would be appreciated!
Here is a couple photos of the cam and engine
