Yes the 4.10's will definitely help your 60 especially with the 383 trying to get that thing rolling. I would go to 4.30's if you are buying new gears, they are a nice compromise between 4.1 and 4.56.
I went from 3.23's in my 69 roadrunner with a 440 running 12.5's most of the time to 4.30's and 1st pass it ran 12.15 and I only made 3 passes and I got it down to 12.09.
That was a street car, 10:1 pump gas 440 with a .509 cam, 3500 stall, 3700# car with me in it.
