Thanks for the info. I will check Schrick out. From my Chevy days, I am acutely aware of "If ya valve, ya gotta ring."
I did a little bit of research last night and found an interesting resource, Try this:
What I learned is that the Euro SOHC cars had 188 HP, and (interesting) that the DOHC engine made 220 (217 in US trim) and was available with a 5 speed. Now that would be the combination to have.
Click! Maybe a '89-92 M104 will drop in the '86? There are plenty of complete engines in junkyards at reasonable prices.
Has anyone out there done this swap or looked into it?
