Horse Power

Your poinst about "power" are good. I completely agree that increased horse power is best done in moderation. All I really want is to make up (as much as reasonable) for what I'll loose in off the...

Changing Axel Ratio

I agree, after reading all that can go into a tranny swap, that changing the differential ratio is the way to go.
