First, I can't believe someone actually replied to this thread. Its been out here for months. What model year engine are you planning on using and what is the actual compression ratio? I want to pull the original engine out of my 83 280 SL and put it in storage. There are a million 2.8 engines in the junkyards here in Houston. I would appreciate an opinion on what car I should use as an engine donor for the rebuild. Right now I can pull one from a 78 280SE.
For the blower, I was planning on adapting one of these:

I was going to try to adapt as much of the stock EFI from the 280 SL as possible to the 280SE engine. Whaddya think?
