I have a 528i and the time has come for a rebuild. My engine has finally died :( The question is what should I rebuild? the 2.8L or a 3.5L? I have a Euro 4-barrel carb setup for the 3.5 so converting should be easy enough. (No fuel injection or computers to worry about) Which engine will give me the most bangs for the buck also taking into consideration the weight differences of the engines. Right now I'm leaning toward the 3.5 and considering stroking it to a 3.8 any ideas on this? Thanks to all who reply, AJ
