Recently, a reputable builder over on the 385 series forum on network 54 weighed his 550" stroker 385 series engine. It came in under 600lbs (550-560 I think) using a production block and aluminum heads. That's less than a 2003 Cobra engine, and only a tad more than a comparable (similar materials, aluminum heads) windsor.

The weight difference isn't much when using modern components; I think most of this weight thing is psychological...the scales don't show a big difference. I'd compare this small vs big block weight argument to arguing that installing a 3.8L V6 instead of a 5.0L V8 is a good move because it saves weight. The modern V6's make nearly as much power, so why not? Think of it in that light and it doesn't make much sense. If power to weight ratio was everything, we'd all be putting turbo 4-bangers into our cobras to save weight; much like the rally cars do.
