Undy just made the best case for why someone, who is not wanting monster power, should drop in a 390 on a Cobra build. Because it is easy to pull it out and slide in a real big block with real power. A Windsor stroker is lighter, cheaper, and easier to do, but if you ever decide to move up to a 427 based FE stroker, its going to be a costly pain in the butt conversion. Fact is, I would sell my SB Cobra and either pick up another with a FE already in it, or build one from scratch.
