I had access to a '71 240Z that is completely stock except for Panasport wheels and one inch lowering Eibach springs. So these items match my car.
A friend brought over his race car scales, so we weighed both cars, and then I corrected for the amount of fuel in each so the numbers would be comparable.
Here are the stats regarding weight (in lbs), weight distribution (in %), and weight to power-ratio (in lbs/HP):

Can't hope for much better than stock 49-51 weight distribution, weight more toward the middle of the car, and a weight to ratio like that.
