67 Barracuda front brake drums, Alignments and tires

Something is not right, mine will cruise all day at 75 mph to 80 mph smooth as glass. Alignment? tires?
I did have it aligned two days ago, then took the it on the highway for the first time.
Thing is, these guys have old specs so I asked them to add more caster. The specs are what he did but I found specs on this site that you see hand written in the pic, that I'm going to see if they can do that.
What car do you have, and do you know the numbers it was aligned to? What size are your front tires, and do you have a stock setup? I have slightly thicker tie rod ends and sleeves and a brand new manual gear box and new upper and lower ball joints.
