'67 Dart drag car with a rack and pinion swap needs some geometry help
That only helps bump steer. Not steering geometry.
OP states two problems: steering geometry and large angle of the tie-rod to the BJ.
@mod5v shows the fix for the large angle, assuming that's the angle OP references.
The swapped BJ's will give a poor ackerman angle, but that doesn't matter much for a car used mostly in straight lines. Ackerman really only helps in a zero-scrub situation anyway (parking speeds). Cars at high speed benefit from anti-ackerman or something in between depending on tire and actual cornering speed. If his car is already good at going straight, no reason to futz with it. Fixing it might help turn a little tighter at pit speeds, but it's not going to cut the turn radius in half.
Fixing the turn radius with a rack means shortening the steering arms to increase wheel angle. A custom lower BJ housing would be perfect for this, but I'm not sure they exist for dodges. Wouldn't be hard for a decent shop to fab though. Welded 1/4 or 3/8" plate with a threaded ball joint would likely do the trick, and then the height of the steering arm can be placed wherever to fix the tie-rod angle too.
Swapping the whole front end to make a drag car turn better and reduce a rub seems like a lot of money to spend versus wheels with more backspacing and rolling the front fender lips... but that's just me. I'd go with a slightly smaller tire and jack the front end up to get the same fender height and enjoy the increased clearance.
