I've got a 2.8 engine from a 280Z with a rebuilt N47 head for sale. The motor had near perfect compression when I checked it, the head is and even looks brand new. It has a header, complete exhaust, and 5 speed transmission. It was running before I pulled the fuel injection system. You can either carb it, or throw on a stock fuel injection system, or even a Megasquirt, whatever you want. I don't have the manifold/injectors/sensors/throttle body, but I do have all the other stock EFI parts.

I'm asking $500 as that is a very fair amount, since stock ones have sold for that much w/o any exhaust, headers, rebuilt parts, trannys, etc.
