What are the practical (including cost) options to change the ring and pinion gears to "lengthen" all the gears so as to optimize a more powerful engine?

A one-day-newbie to gears with a more powerful engine, I can attest to the line of thinking Keith is pursuing. Yesterday was the first time I have driven my newly sorted 3.0. for miles (in breakin mode under 4K of course)... and I can tell you that first gear on a 901 box is useful if your hair is outta whack and needs a good inertial resortment toward the back of one's head.
I will spend a portion of today to understand this phenomenon better. Sidebar: Perry's beautiful work on the harness went in without a hitch or spark / no need to tamper with that kind of work and support / same goes for his pal Rich Johnson. Excellent quality on the shift and accelerator linkage. Happy Memorial Day and take time today to remember why we have the luxury of time behind the wheel of a 914.
