the smallbock with aluminum heads is less then a 930 weight.
on the theory of high vs lower mass I guess I would rather drive around with a woman in the seat next to me with a big rack and small rear rather than a woman with no rack and a large rear or in this case no woman at all because there can be no weight above the centerline of the crank.
.......it's just a car and 20-50 above the crank is nothing that my driving skills could detect.
neat engine...... is it in you 911?
just having fun.
