The new cam is better then the bigger one you had for your combo.
Did you have the vert worked on as well?

If I were to do any changes, id install that cam at a 100 LIC and go with a 5000 vert. Your Tight carb proximity to the hood isn't helping things either. But, maybe your new hood is on now.

You gave your new mph for the 1/8th as well as the 60 ft. What was your ET? Your 1.41 to 1.44 60,s are soft IMO for your combo. Get that fixed and your in the 9,s.

Edit; you also asked about gear. You have to much gear IMO. I would lose the 31 x 14,s and go with 32 x 12,s or even 32 x 10,s with those 4.56,s You shouldn't need that much tire with your 3000# combo
