Good info.. raised a question or two out of mine concerning pressures, with the poster. I'm still rolling things around in my head about that.
From what read, they have a different angle than stock to make them work for our cars, making the pitman arm not parallel to the frame. I don't believe this is related to the idler bumping the pan at full lock. I honestly believe it's be cause TTI states that you have to ream the bolt holes to .800ish to allow for clearance. Talk about voiding some warranties lol. Anyway, this is done to allow the box to move left a 1/4" or so. By doing this, it drags all connected steering components to the left, moving the idler a 1/4" closer to the pan. So at full lock, I just barely touch the pan. If the box hadn't needed to be moved, I believe I'd have 1/4 or 3/16 idler to pan clearance. Just everything combined really.. moving the box left, scooching the motor right and maintaining correct crank center height creates the perfect storm to bump that pan. Reality is.. TTI could have done better with the A body fit
This one reason Holley doesn't really have this issue, when using their headers.. Box stays in stock location and the arm doesn't his their pan.
