The new box requires a lot less effort then the stage 3 box it replaced. In that respect, I liked the other box better. That's why I may try the 2gpm valve.
What I like is that the new box is a lot tighter. My old box had around 30 degrees of play at the center position. I tried adjusting the lash, but it did not improve at all. It just made it feel stiff. It drove me crazy, so that's why I replaced it.
In hind sight, I should not have had my original box rebuilt. I think it had 170k on it. I had a lower mileage box from a 72 Cuda that would have been a better choice.
