$400 for a weight savings of 25lbs, hmmm, kind of expensive, pound per dollar spent.

On the FE motor in general there is a LOT of weight you can save. Aloy water pump, heads and intake come to mind! And THAT weight is FORWARD weight. Much better pound per dollar spent return on your investment.

As part of a "total diet" plan the trans is a worthy investment. By itself I'm not so sure. It does have a certain "cool factor". But being as a trans is "hidden" I'm not sure I would pay $400 more just for that reason!

While on the subject of "weight" reduction consider this:
You have to save THREE pounds of "static weight" (your butt in the seat, lighter trans, heads, etc) to equal the benefit of ONE pound of rotating weight.

Saving ONE pound of wheel/tire weight (rotating weight), for instance, is like saving THREE pounds of "body" weight. Consider the impact of an alloy flywheel then, or a carbon fiber drive shaft, or how about an alloy flywheel? Rotating mass, THATS where you would maximize your dollar per pound of weight saved!
