New QA1 UCA's on my 70 Duster. Passenger side doesn't have enough camber

Those QA1 uppers are designed to move the upper ball joint back for high speed stability. If he's using stock specs he may not be able to get the upper eccentric to work. But as pointed out you don't want stock specs. Use the skosh chart and put a jack under the K frame and jack the car up an inch from the rest position. This is closer to where the front end will be when your doing top speed.
