Its done, i went for a cruise about a half hour ago. It shimmies at 75!
It is night & day better than it was before. The slop in the old box was damn near the whole problem. Its a little twitchy, might be toed in a smidge? Its god damned cold outside, theyre (big) old bias plys, and its got a locker in the rear. Its not gonna be perfect!
I still want to triple check the toe-in tho and see if i can get dialed in a little better.
So just cruising down the road, i cant tell a difference in the power of the box with the way Redhead has it ported, as opposed to the way PSC did it. I always thought porting the control valve was the 'correct' way to do it, but RedHead knows a lot more about this stuff than i do! The real test will be the next time i get a chance to play on some rocks with the tires aired down.
