My friend John has finally finished his Frankenbeast. It started out life as a 635CSi 5 speed, now it's a Corvette powered 6 speed. The engine and tranny are GM, all else is still BMW. The V-8 ended up about 100 lbs lighter than the M30, but the 6 speed is 50 lbs heavier, so it's all worked out pretty good. Of course my camera died at the most inappropriate time so I only have one picture. The custom headers are beautiful. Overall a very nice installation. There is no fan on the front of the engine, just a big electric fan on the front of the Behr radiator. There is a small temperature rise sitting in traffic, but not to an overheat condition. He's still working on that one. With the hood closed, you cannot tell what lurks underneath. It just looks like a nice e24 with 5 spoke 17" wheels. Well, there is that V-8 burble that's hard to conceal. Yes, it's a rocket!!!!
