Test driven. Boy is it ever a LOT quicker. It actually wants to hook up more, of course. I could make it roast um, but I'm afraid now I'll break somethin. lol It has a very, very, VERY light whine on decel, but I'm callin it good. It could simply be because it's turnin the drive shaft so much faster. More likely, the pinion depth is out just a skosh, but I'm leavin well enough alone. I'll have to get Kitty to shoot another video next time we take Vixen to town. Kitty's not feelin good today, so it probably won't happen today. I'm callin it a huge success!
